STEM | Today at Â鶹ÊÓƵ | Â鶹ÊÓƵ /u/news Thu, 05 Nov 2026 20:25:42 -0500 en-US hourly 1 Hwayeon Ryu advocates for STEM workforce and federal funding on Capitol Hill /u/news/2026/01/14/hwayeon-ryu-advocates-for-stem-workforce-and-federal-funding-on-capitol-hill/ Wed, 14 Jan 2026 15:44:14 +0000 /u/news/?p=1036884 In January 2026, Associate Professor of Mathematics Hwayeon Ryu traveled to Washington, D.C. to participate in #MathSciOnTheHill, a national advocacy event organized by the and 17 partner mathematical societies. The event brought together more than 290 mathematicians from across the United States to meet with members of Congress and their staff and to advocate for policies that strengthen STEM education and the U.S. STEM workforce through sustained federal investment.

The group of 290+ mathematical sciences community-educators, students, and researchers from 47 states gathered as one group to take their voices to Capitol Hill to advocate for research and the importance of mathematics.

Participants were organized into advocacy teams based on geographic location. Ryu and her team (of North Carolina 4th Congressional District) met with the offices of U.S. Senators Ted Budd and Thom Tillis through their legislative assistants and held an in-person meeting with U.S. Representative Valerie Foushee of North Carolina’s 4th Congressional District. In each meeting, Ryu participated in the discussions focused on STEM education and continued federal funding, through the National Science Foundation (NSF), Department of Energy (DoE), and National Institutes of Health (NIH), to sustain and strengthen the U.S. STEM workforce.

Associate Professor Hwayeon Ryu (second from the right) met with the legislative correspondent for Senator Ted Budd during a mathematics advocacy visit to Capitol Hill.

The conversations emphasized that mathematics is foundational to nearly every STEM field, including artificial intelligence, biotechnology, cybersecurity, climate modeling and advanced manufacturing. While often operating behind the scenes, mathematical sciences provide the analytical framework that enables innovation across STEM fields. Federal support, such as NSF, ensures that students receive high-quality training in quantitative reasoning, data analysis, and interdisciplinary problem-solving—skills that are increasingly critical in a rapidly evolving economy.

As a faculty member at a primarily undergraduate institution, Ryu highlighted how her NSF-supported research directly benefits students from various STEM majors at Â鶹ÊÓƵ. NSF funding allows faculty to engage undergraduates in authentic research experiences that integrate teaching and scholarship. Through these projects, students gain hands-on experience working with real data, computational models, and collaborative research teams. Many of her former and current students have gone on to graduate programs in STEM, federally funded research positions, or STEM careers in industry and healthcare, contributing directly to the national workforce pipeline.

U.S. Representative Valerie Foushee (second from the left) talked with Associate Professor Ryu (far right) and her team at the meeting.

The meetings also underscored the important role that primarily undergraduate institutions play in educating a diverse STEM workforce, including first-generation students and those from rural or underserved communities. Investments in NSF programs that support undergraduate research help expand access to STEM pathways and ensure that talent from a wide range of backgrounds is represented in the nation’s scientific workforce.

By participating in #MathSciOnTheHill, Ryu helped amplify a collective message from the mathematical sciences community: continued federal investment in mathematics education and research is a strategic investment in the strength, adaptability, and competitiveness of the U.S. STEM workforce.

The Capitol Hill visit highlighted how faculty advocacy can connect classroom and research experiences at Â鶹ÊÓƵ to national conversations about innovation, economic growth, and workforce development. Her Capitol Hill visit was supported by the American Mathematical Society.

Â鶹ÊÓƵ’s ‘Legally Blonde’ goes high-tech with robotic co-stars /u/news/2024/10/21/elons-legally-blonde-goes-high-tech-with-robotic-co-stars/ Mon, 21 Oct 2024 17:50:53 +0000 /u/news/?p=998651 Innovation will take center stage when the musical “Legally Blonde” opens at Â鶹ÊÓƵ this weekend. For the first time, robots will share the stage with live actors.

Fans of the 2001 movie-turned-musical are no doubt familiar with its loveable canine sidekicks: the iconic Bruiser, main character Elle Woods’ chihuahua, and Rufus, manicurist and confidant Paulette Bonafonté’s bulldog.

A robot in a chihuahua costume
Bruiser, Elle Woods’ iconic chihuahua in “Legally Blonde” is a quadruped robot costumed in a flocked silicone mold designed by engineering major Zoe Scherpbier ’25.

In a collaboration between Â鶹ÊÓƵ’s Music Theatre Program and the Department of Engineering, the show’s co-starring dogs will be played by quadruped robots programmed, costumed and controlled by engineering students. The musical follows heroine Elle Woods as she journeys from UCLA to Harvard Law School, tackling stereotypes and navigating sexual assault and harassment, on her way to becoming a lawyer.

“I think Bruiser and Rufus are definitely going to steal the show,” Emily Stober ’25 said, laughing. A music theatre major from Hickory, North Carolina, Stober plays Elle Woods in Â鶹ÊÓƵ’s production. “This is the perfect balance of having a live animal onstage versus an inanimate object. It still has that ‘breath’ to it, and it’s a tool I think could be used more in theatre and music in the future.”

“Legally Blonde” opens Friday, Oct. 25, at 7:30 p.m. in McCrary Theatre in Â鶹ÊÓƵ’s Center for the Arts. The musical runs for five additional showings on Oct. 26, Oct. 31 and Nov. 1-2 at 7:30 p.m. and on Sunday, Oct. 27, at 2 p.m. Tickets are available at .

The creative partnership showcases the kind of interdisciplinary collaboration that’s a hallmark of Â鶹ÊÓƵ’s approach to education, where ideas and input from a wide range of academic perspectives are sought out and celebrated. It’s also illuminated new career paths for some of the students involved.

It began when Assistant Professor of Music Theatre Courtney Liu, who is directing “Legally Blonde,” and Assistant Professor of Engineering Blake Hament were brainstorming ways to blend their fields at Â鶹ÊÓƵ. Liu researches the psychology of performance, and beyond that desires to provide Â鶹ÊÓƵ’s budding professionals with broad experiences that will enrich their careers. Hament’s research includes developing quadrupeds and other robots for use as service animals.

The project advances solutions in both disciplines. Trained animals are expensive and can be unpredictable during live performances. The public often finds quadruped robots’ appearance unsettling but finding ways to make them appear more lifelike could advance their use as service animals. Liu and Hament received a grant from the Â鶹ÊÓƵ Fund For Excellence in the Arts and Sciences to pursue the collaboration.

‘So many doors have opened’

Zoe Scherpbier ’25 jumped at the chance to design and fabricate the dogs’ costumes. An engineering major from San Diego, California, she’d completed undergraduate research with Hament in 2023-24 to develop touch-sensitive “fur” for quadruped robots. She also has a theatre background and has sewn since her grandmother taught her at a young age.

“I love theatre. The costumes and the bedazzlement have always drawn my eye,” Scherpbier said. “The actors and actresses in “Legally Blonde” have had such a great reaction to the dogs. They really loved them, and it’s been fun being a part of the community of actors and crew as they work so hard to put on this show.”

Since the summer, she’s spent one day a week at the (UNCSA) in Winston-Salem, which hosts one of the nation’s top animatronics programs. With graduate student Carlitos Ayma Gonzalez, she’s designed silicone molds and flocked them with “fur” to look like real dogs. In the process, Scherpbier discovered a new career path and plans to pursue graduate studies in animatronics at UNCSA.

“This has broadened the horizons of what I can do with an engineering degree, seeing that there’s a place I can use what I’ve learned in engineering and in the arts” Scherpbier said. “Being an Imagineer at Disney would be so cool. So many doors have opened through working with Dr. Hament.”

Scherpbier worked with Liu and Hament to design the costumes for function and aesthetics. Rufus’ dog costume posed the greatest challenge. The dog has been transformed into a pitbull mix for Â鶹ÊÓƵ’s production to allow the robot to move beneath the costume and for quick battery changes between scenes.

The more than 30 other students in the Department of Performing Arts staging “Legally Blonde” were enthusiastic when they learned that engineering students would be part of the production. They’ve put in more than 25 hours a week rehearsing and preparing the show and were ready to welcome new team members into their community.

“I was really excited to work with the engineering department,” Stober said. “So much of acting is just play, and things like this keep it exciting for us actors. It’s been fun to have students who don’t know theatre as much join us in this process. It’s been interesting to see them learn our lingo and us learn their lingo, and I’ve appreciated being part of a collaboration I might not have had elsewhere.”

Liu attributes that to the kinds of students Â鶹ÊÓƵ recruits to its music theatre and performing arts programs: ambitious, highly talented and interested in having broad educational experiences in the liberal arts unavailable at conservatories. Â鶹ÊÓƵ’s Music Theatre Program is regularly recognized as among the best schools in the nation for music theatre.

“These students understand the connection between responsibility, hard work and true collaboration,” Liu said. “I am absolutely in awe of their dedication, grit, thirst for excellence, athletic prowess, artistic depth and commitment to each other and their craft.”

Expanding opportunities for students

Behind the scenes, other engineers have entered the spotlight. Jack Delucco ’26 programmed the robot controls. Maggie Dion ’26 and Amalie Keefe ’26 will control the dogs movements, reacting to dialogue and queues, during the staged performances.

Dion, from Attleboro, Massachusetts, is controlling Bruiser. Keefe, from Durham, North Carolina, is handling Rufus, whose onstage role is slightly more complex. In the wings with the technical crew, they manipulate the robots to perform dances, nods, spins and wags alongside actors onstage. Dion previously researched quadruped robots with Hament, exploring adding “dog ears” of different shapes to make them look friendlier. Keefe researched the creation of a voice module that would turn human commands into code that would trigger the robots’ actions. Both have benefitted from seeing the time and effort that goes into staging a musical, and each are interested in future robotics research and collaborations.

“This has taught me that engineering and robotics can exist in unexpected places,” Dion said. “I wouldn’t have thought I’d be involved in a play this year, but now I see that engineering can be in other parts of life.”

Though engineering and music theatre may not at first seem complementary, Liu and Hament have discovered that they employ similar problem-solving methods and constraints in each of their disciplines. Infusing new perspectives also brings better solutions, they said.

“We’ve seen concern globally that some engineers are developing technology that has downsides or risks they hadn’t considered,” Hament said. “If we bring more voices into the conversation and work with people outside our field, that will help steer AI and technology in better directions.”

The professors remain excited by the prospect of advancing future collaborations and exposing students to disciplines outside of their majors.

“These kinds of collaborations expand opportunities for our programs and students,” Liu said. “In theatre, they allow us to explore additional material and works we might not have. We’re always looking for creative solutions so we can create bigger art.”

When “Legally Blonde” ends its run, Liu and Hament expect to publish an article about the experience with Â鶹ÊÓƵ undergraduates as co-authors.

Lumen Scholar Anna Altmann ’23 tackles a dirty job for science and the environment /u/news/2023/03/28/lumen-scholar-anna-altmann-23-tackles-a-dirty-job-for-science-and-the-environment/ Tue, 28 Mar 2023 18:49:11 +0000 /u/news/?p=943501 It’s 3:30 p.m. on a Wednesday and, inside a McMichael Science Center chemistry lab, Anna Altmann ’23 is smoking her second cigarette in a half-hour.

With gloved hands, she places the cigarette into a nozzle attached to an Erlenmeyer flask, lights it and — using a plastic syringe — draws air through the flask and a couple feet of tubing. Altmann leans away from the hood as a faint smell of tobacco smoke fills the lab.

“It’s very smelly, but this just being a couple of cigarettes, it won’t get too bad,” she says.

“But if you’re in here for a long time and doing lots of them, you’ve got to schedule a shower after,” her mentor, Associate Professor of Chemistry Justin Clar, says. Altmann nods and smiles in weary agreement.

Scientific research can be a messy process. Sometimes it’s downright dirty.

To better understand how much and what kinds of metals are leaching from and being adsorbed by littered cigarette butts, Altmann knows this all too well. The Goldwater Scholar, Lumen Prize recipient and Honors Fellow has spent the last two years collecting and studying cigarette butts and using her improvised smoking apparatus to create fresh ones.

Cigarette butts are more than just litter. They’re a global problem. Each year, an estimated 4.95 trillion cigarette butts are littered, ending up in runoff, polluting oceans or languishing in the dirt. Once they’re tossed, they do more than linger. All those butts are actively releasing and adsorbing trace metals, influencing the global cycling of these elements.

A chemistry and computer science double major, Altmann became interested in environmental chemistry before college. A native of Burlington, N.C., she completed general chemistry with Clar while still in high school. As an undergraduate searching for honors thesis topics related to chemistry and the environment, Clar — an expert in the study of metals and nanoparticles in environmental systems — recalled questions he’d had about littered cigarette butts since his post-doctoral work with the EPA in Cincinnati.

Altmann dove into existing research and discovered gaps in what had been studied about the release of metals from cigarette butts, namely that cigarettes had been tested in labs but not collected from litter. A light went on and Altmann had the nut of her research question: What and how much are all of these littered butts releasing into or adsorbing from the environment?

“She came up with this comparison on her own. Since then, she’s chosen everything we’ve done with solutions, solvents, time periods and collections, everything,” Clar said.

Altmann’s exploration of that issue earned awards nationally and at Â鶹ÊÓƵ.

In her sophomore year, she was awarded the prestigious Goldwater Scholarship, one of the most selective awards in the country given to undergraduates intending to pursue research careers in STEM. She was only the second Goldwater Scholar from Â鶹ÊÓƵ to win the award as a sophomore. That same year, she was awarded the Lumen Prize, Â鶹ÊÓƵ’s top research award that annually provides 15 rising juniors with $20,000 to advance their undergraduate research projects.

In addition to paying for necessary materials during a period of pandemic-related rising costs, those prizes bolstered Altmann’s confidence in her research and afforded opportunities she may not otherwise have had. She attended the Society of Environmental Toxicology and Chemistry Conference, twice attended American Chemical Society conferences — where she will present her research later this month — and traveled to Rice University to give an invited talk.

“Having that money allowed her to network with a lot of people, which is going to open doors for her in graduate school,” Clar said. Altmann has already been accepted to a number of environmental engineering doctoral programs, including those at Yale, Duke, Clemson and Carnegie Mellon.

As demonstrated by the improvised tube-and-flask method of creating fresh specimens in the lab, Altmann went to great lengths to gather enough samples to glean solid data. That included rallying volunteers over Homecoming Weekend to collect butts around and near campus.

“Â鶹ÊÓƵ is a non-smoking campus, so we weren’t sure if we would find enough, which is why we collected on the day of a big football game when we thought people might be tailgating. We were surprised how many we found,” Altmann said.

That day, they collected four gallon-sized bags of filters — a few thousand butts weighing in close to 2.5 pounds — in various states of degradation. Altmann spent the next few weeks sorting them by their condition, from freshest to most degraded. She analyzed them for metal content and put others in chemical solutions to test for leaching.

Preliminary analysis shows that cigarette butts are both leaching and adsorbing metals. Sodium, magnesium, potassium, calcium and aluminum were leaching in the highest concentrations. The more degraded the butt, overall, the lower the concentration of leaching. Chemical solutions didn’t play a significant role in how much or which metals leached.

“As of now, the data indicates that cigarette butts from the environment contain between 11 and 16 metals depending on the level of degradation, with the most degraded butts containing metals not found in artificially smoked or less degraded samples,” Altmann said. “This indicates that the butts are picking up metals from the environment, which is potentially problematic because of the balance of naturally occurring metals in soils. Chromium, nickel and lead were in the most degraded butts but nowhere else, and aluminum, iron, and zinc were higher in more degraded butts than in the less degraded butts.”

Some of the leached metals, like aluminum and zinc, can cause health problems.

“We are most concerned about arsenic, mercury and lead, and we are sending samples to another lab for external analysis of those metals. If we find them, that would be more concerning to us health-wise,” Altmann said.

She hopes her future research will involve environmental remediation.

“I’m really interested in looking at how to remove metals from water. In this project, I was looking at how metals enter water from a new source, but I’m more interested in aspects of remediation,” she added.

Altmann initially found the research process intimidating but it resulted in the most rewarding part of her college career.

“Just because something is new to you doesn’t mean you can’t do it,” Altmann said. “I was worried I would fail at research and worried it would be difficult to find a mentor and work on a long project. I’m so glad I pushed through that fear.”

Leaving her comfort zone developed both self-confidence and research skills.

“She’s taken a lot of ownership of the project and I just make sure what we’re doing is in line with the big-picture goals,” Clar said. “It turned into her coming to me and saying, ‘I’m going to do this,’ which is an indicator that, instead of me telling her what to do, she’s directing where it’s going and I’m just making sure we stay on the tracks.

“I don’t have to worry about Anna. She just chugs along and gets the job done.”

As for smoking, Altmann has no plans to pick up the habit and is glad her days of lighting cigarettes in labs are behind her.

“If this project taught me one thing, it’s that I’m surer than ever that I won’t smoke,” Altmann said. “Having to smoke those cigarettes for hours upon hours and seeing the gunk that filled the tubes was disgusting. So, while I have loved my research, I am happy to not smoke anymore.”

Bernard Reinckens ’16 engineers oceanic defense systems with Liquid Robotics /u/news/2023/02/17/bernard-reinckens-16-engineers-oceanic-defense-systems-with-liquid-robotics/ Fri, 17 Feb 2023 16:50:34 +0000 /u/news/?p=939889 Electronics design, testing and integration, and quality engineering: On any given day, Bernard Reinckens ’16 fills all these roles and maybe a few more as an electrical engineer with Liquid Robotics.

Liquid Robotics is a subsidiary of Boeing, developing defense technology that uses sensors, connectivity, and cloud computing to collect and communicate ocean data in real-time. One of its products is the Wave Glider, an unmanned solar- and wave-powered vehicle that gathers data in conditions and places previously too costly or challenging to navigate. Reinckens is the lead REA (responsible engineering authority) for all of the Wave Glider’s printed circuit board assemblies. His duties entail designing new boards, troubleshooting faulty boards and the development of new test procedures.

“Right now, our electrical engineering team is small. There’s only a handful of us, so we do it all,” Reinckens said. “Every day is different.”

Reinckens graduated from Â鶹ÊÓƵ’s dual-degree engineering program, earning a B.S. in Engineering-Physics from Â鶹ÊÓƵ and completing his B.S. in Electrical Engineering at Washington University in St. Louis. He later went on to earn his M.S. in Electrical Engineering from Villanova University in 2021.

Â鶹ÊÓƵ offered the opportunity to grow his STEM skills in smaller classes with professors who are passionate about teaching and provided the opportunity to pursue extracurricular interests in sports and service. But what Reinckens values most about his time at Â鶹ÊÓƵ was the emphasis on effective collaboration.

“Â鶹ÊÓƵ prepared me for all the other schooling and classes I took at my engineering and graduate schools, and it showed me that as technical as engineering can be, it’s really about being able to effectively communicate and work with others,” he said. Reinckens recalled the numerous late-night study sessions with classmates on the STEM floor in Staley Hall.

After graduating in 2016, he was initially hired by Boeing in St. Louis as an electronic design and analysis engineer on the F/A-18 program. Over the next six years, he worked a variety of roles at Boeing Defense including designing power supplies for flight control hardware, testing electronic components for quality and safety, and leading projects for INS/GPS and navigation mission computers.

At Liquid Robotics, the best part of his job is working with colleagues and knowing the work they are doing has significant outcomes in the maritime industry.

“There’s always something more and new to learn, and it’s constantly evolving and changing,” he said. “Â鶹ÊÓƵ and all the schools I attended showed me that learning is a contact sport and that it’s continuous. My desire to learn is what keeps me active long after graduating college. It challenges me to become a better problem solver and, consequently, a better engineer.”

David Jennings ’23 creates virtual reality game that preps users for job interviews /u/news/2022/09/27/david-jennings-23-creates-virtual-reality-game-that-preps-users-for-job-interviews/ Tue, 27 Sep 2022 13:20:37 +0000 /u/news/?p=925484 What if playing a game could help you land your dream job?

This is the question David Jennings ’23 is exploring as he creates and tests a virtual-reality game designed to train users for the job interview process. Players level up by scoring well in areas like researching the company and position, collecting materials to bring into the interview and following up afterwards.

With Assistant Professor of Computer Science Pratheep Paranthaman as his mentor, Jennings is exploring the concept of gamification — using games in a non-gaming context — to motivate users. They will study user interaction in the spring, including using EEGs to measure brain activity to identify stressful or exciting aspects of the game and interview process.

“We’re trying to see how gamification affects different applications and using the framework of a job-interview application,” Jennings said. “We want to identify specific aspects of gamification that help people prepare for interviews, to find what’s effective and what’s not and point the way for future applications to take inspiration from this research.”

Jennings’ prototype application to gamify the job interview process includes preparation exercises like wardrobe selection.

Jennings, a computer science major with a game design minor, is also an Â鶹ÊÓƵ College Fellow and Odyssey Scholar. He embarked on the research as part of the College Fellows program, which culminates in a closely mentored, two-year research project. He presented his research paper, “Conceptual Design and Early Prototypes of a Gamified Virtual Reality Interview Training Application,” virtually at the sixth World Conference on Smart Trends in Systems, Security and Sustainability held in London on Aug. 27. Jennings previously presented his research in SNCURCS (State of North Carolina Undergraduate Research and Creativity Symposium) in fall 2021.

As part of the development process, Jennings designed an initial prototype system in virtual reality. While studying abroad in Copenhagen this semester, Jennings is in the process of refining the system for a complete VR experience.
He began his project in spring 2021 after participating in a VR research project also mentored by Paranthaman.

“That was my first experience with VR technology and the inspiration for my own research,” Jennings said. “We looked into areas where VR is used outside of gaming. There are tons of venues for health education” for nursing and medical professionals. “Almost everyone goes through a job interview and a lot of people aren’t sure what to expect, especially if it’s their first interview.”

Paranthaman has been an ideal mentor, Jennings said, giving him the freedom to explore areas of interest while remaining available when questions or hurdles arise.

“He’s been able to guide me without holding my hand,” he said. “I’ve improved as a researcher and a programmer because of him.”

Jennings’ accomplishments are the result of his ambition and work ethic, Paranthaman said.

“David has been instrumental in developing this research idea from the ground to a functional prototype,” Paranthaman said. “At the start of the research process, he had a vision and equipped himself with the resources — such as learning about the state-of-the-art research and development process — to transform the vision into a working system.

“Virtual reality development is a challenging area with multiple complications, such as device configurations, ever-changing software versions and usability factors. David worked with all these constraints and adapted himself toward the challenges in this research and constantly progressed to the outcomes he envisioned.”

Jennings is planning a career in game design and programming.

Alumni in Action: Danielle Cooke ’16 makes medical miracles happen /u/news/2022/09/16/danielle-cooke-16-makes-medical-miracles-happen/ Fri, 16 Sep 2022 19:51:33 +0000 /u/news/?p=925133 Danielle Cooke '16 poses in front of a city skyline
Danielle “Dani” Cooke ’16 didn’t expect to pursue engineering until an orientation-week session sparked a passion around biomedical engineering. She now trains neurosurgeons how to use technology to perform noninvasive brain surgery.

Danielle “Dani” Cooke ’16 sees miracles every day. Even better, she helps make them happen.

As a clinical applications specialist in neurosurgery for , she trains neurosurgeons on how to use technology to perform noninvasive brain surgery using the company’s Exablate Neuro system to treat patients suffering from tremors due to conditions like Parkinson’s disease.

“Some patients have suffered from tremors their whole lives, and then — within a matter of hours — their hands are still. It’s one of the most rewarding things in the world to witness,” Cooke said. “It amazes me every day. I have truly found my dream job.”

Exablate Neuro uses focused ultrasound waves to target a small area in the thalamus, heating it and causing a small lesion which interrupts tremor pathways. The procedure is FDA-approved to treat essential tremors and Parkinson’s-induced tremors.

Cooke graduated from Â鶹ÊÓƵ’s dual-degree engineering program, earning a Bachelor of Science in bio-physics/biomedical engineering from Â鶹ÊÓƵ and continuing at Columbia University where she earned a Bachelor of Science in Biomedical Engineering.

“For my career, Â鶹ÊÓƵ in particular offered me two of the most essential and foundational tools,” Cooke said. “First, Â鶹ÊÓƵ professors instilled in me the fundamental concepts of engineering in creative ways. I am constantly reminded of certain classes and projects I completed in those three years.

“The second is the ability to communicate, which I believe is crucial to being a successful engineer, and I think often can be overlooked in engineering curricula. At Â鶹ÊÓƵ, there’s not only a natural exposure to building communication skills through the Core Curriculum, but also within the engineering program: through poster presentations, working on team projects and even visiting an elementary school to teach engineering basics. All of these experiences and more taught me how to effectively communicate my ideas and thoughts.”

Those skills are vital to communicating with people at the many different knowledge levels — surgeons, physicians, patients and fellow engineers — she encounters in her role at Insightec.

Cooke wasn’t planning to be an engineer when she enrolled at Â鶹ÊÓƵ. Though plotting a course toward medical school, during orientation she attended an interest-session about engineering led by Associate Professor Emeritus Rich D’Amato.

“He started talking about biomedical engineering, and it was like the doors opened up and sunlight came in,” Cooke said. “After that, I knew it was exactly what I wanted to pursue. I took that feeling and changed my course-load a few days before classes started. It was one of the best things that’s ever happened to me.”

She discovered her interest in the brain — “the biggest puzzle left to solve” — during a summer internship at Burke Rehabilitation Hospital in White Plains, New York, as an assistant researcher in a project examining transcranial magnetic stimulation’s positive effects on spinal cord injury patients. In her last year at Â鶹ÊÓƵ, she completed a capstone project with Associate Professor Scott Wolter researching carbon nanotube coatings for deep brain stimulation in Parkinson’s patients.

She advises Â鶹ÊÓƵ students to take advantage of opportunities to study abroad and immerse themselves in the range of subjects available to them.

“It changed my life going to that one seminar,” Cooke said. “Go outside of your comfort zone to learn as much about as many fields as possible, even if you’re sure you have a path already. This is a unique experience and time in your life, you may find something new that’s exactly what you’ve been looking for.”

Â鶹ÊÓƵ creates Department of Engineering as program gains prominence /u/news/2022/08/01/elon-creates-department-of-engineering-as-program-gains-prominence/ Mon, 01 Aug 2022 19:56:58 +0000 /u/news/?p=920678 Reflecting years of growth in the program and marking a milestone in the Boldly Â鶹ÊÓƵ strategic plan, Â鶹ÊÓƵ established the Department of Engineering on Aug. 1.

The formation coincides with the opening of the first two buildings in Â鶹ÊÓƵ’s Innovation Quad, a state-of-the-art center for engineering and physics research and cross-disciplinary collaboration featuring 60,000-square-feet of cutting-edge lab and prototyping spaces.

Crews prepare landscaping around Founders Hall and Innovation Hall, the first two buildings of the Innovation Quad, which will open later this month.

Associate Professor Scott Wolter will serve as the department’s first chair. After years of strategic growth in enrollment, curricula, and programming, as well as significant attention by university leadership to advancing excellence in Â鶹ÊÓƵ’s STEM programs, the department is primed to flourish, Wolter said.

“We want to be a nationally recognized small engineering school,” Wolter said, echoing an objective of the Boldly Â鶹ÊÓƵ plan. “Our goal is to graduate around 100 students in each class with a solid academic foundation and strong engineering skills. We anticipate that enrollment will continue to grow in the near future to meet this target. With the excitement of the new learning spaces and spaces dedicated to collaboration, our program is poised to provide the type of innovative engineering education to meet the challenges of the 21st century.”

The transition to a department comes as the program expands to offer additional courses and degree concentrations, made possible by faculty expertise and the cutting-edge facilities of the Innovation Quad.

Â鶹ÊÓƵ’s engineering program has been part of the Department of Physics since 1999, when the university partnered with N.C. State University to offer a dual-degree engineering program. That program grew to count nine partner institutions, currently including NCSU, Georgia Tech, Clemson University, Penn State and the University of Notre Dame.

Evolving a distinctive brand of hands-on and project-based learning infused with liberal arts perspectives, Â鶹ÊÓƵ launched its own four-year Bachelor of Science in Engineering major in 2018. Enrollment has steadily grown since. It graduated the first three students in 2020. In 2022, eleven graduated with the degree. This fall, 48 incoming first-year students will join the program for a total of 123 students in the four-year and dual-degree tracks.

That growth indicates the unique strengths of Â鶹ÊÓƵ engineering, said Gabie Smith, dean of Â鶹ÊÓƵ College, the College of Arts and Sciences.

“Â鶹ÊÓƵ’s engineering curriculum is truly innovative, providing a rigorous preparation in engineering skills within the rich context of a liberal arts education,” Smith said. “Our undergraduates develop the technical prowess, broad critical thinking and collaborative dexterity needed to solve complex problems and thrive in the field.”

In addition to the general engineering B.S., students can concentrate in biomedical engineering, computer science, and — beginning this fall — environmental engineering. Several engineering minors are also in development. This fall, the interdisciplinary Engineering Design Minor will begin enrolling students in a curriculum that equips non-engineering majors with foundational engineering skills applicable to a broad range of disciplines.

Associate Professor Sirena Hargrove-Leak joined Â鶹ÊÓƵ in 2004 as the program’s second faculty member with Associate Professor Emeritus Rich D’Amato. She coordinated the four-year degree through this spring. She and Wolter stressed the shared mission of continuous improvement in the program by faculty and staff.

“We’ve expanded in terms of the breadth of options for our students, as well as the depth of our curriculum. We are always working to strengthen our courses,” Hargrove-Leak said. “In 2004, we couldn’t envision a school of engineering, but the program has been improving, progressing and growing continuously, so now it is clear that it is possible.

“One of the most beautiful things about that is that the gains engineering is experiencing aren’t isolated to the program. They extend to the entire university community. We expect to attract different kinds of students and I’m excited that everyone stands to benefit,” she added.

Among strategic milestones in the last few years, Â鶹ÊÓƵ’s engineering program:

  • Completed Accreditation Board for Engineering and Technology’s (ABET) rigorous accreditation process from 2019 to 2022, and a formal announcement of accreditation is expected this fall. ABET accreditation signifies a program’s success in graduating engineers prepared to meet the needs of global employers.
  • Added new faculty and staff, including Associate Professor Bethany Brinkman, Assistant Professor Will Pluer, Lab Manager Matthew Banks and Director of Engineering Outreach John Ring.
  • Convened the Engineering Advisory Board, which consists of industry professionals across the country, alumni and parents helping guide the program to excellence.
  • Established the Engineering Scholars program, enrolling up to 20 talented and engaged budding engineers into the program each year. Twenty scholars will enroll in fall 2022.

Wolter is especially proud of the cohesion and shared investment by engineering faculty and staff.

Andrew Jackson ’21 works with Associate Professor Sirena Hargrove-Leak to prepare his 3D-printed rocket for launch.

“The culture of our program is very important. We are motivated and excited about the growth of the program, we all enjoy teaching, and we recognize the value in maintaining close relationships to manage the challenges of the pace and growth,” Wolter said. “Â鶹ÊÓƵ makes it happen. Our leadership enables great teaching and I think everyone in our STEM programs feels their support.”

In addition to opening the Innovation Quad this fall, the university is also extensively renovating Dalton L. McMichael Sr. Science Center’s laboratories, classrooms and meeting spaces to advance studies in the natural sciences. The first phase of those renovations will be completed this month. A second phase is planned for summer 2023.

“These facilities represent new possibilities for our students,” Hargrove-Leak said. “They will have dedicated spaces to do the types of things that they get so excited about: designing and building. They will also be able to test their creations in a more robust way. This facility is going to be life-changing for them.”
