George Mason students present at the second annual Undergraduate Research Showcase in Richmond

At the end of January, three George Mason University students presented their research at the Network for Undergraduate Research in Virginia (NURVa) Undergraduate Research Showcase at the Capitol in Richmond. Now in its second year, the event gives undergraduates from each of NURVa’s member universities an opportunity to present their research to state legislators and fellow researchers alike. Students worked with faculty through George Mason’s Office of Student Creative Activities and Research (OSCAR) to refine their work and apply to the selective event. 

“Having my work accepted into the showcase affirmed that my research is relevant and meaningful, and I was eager to share both the project itself and its broader impact,” said Honors College student Alexia De Costa, a junior applied computer science major studying social robotics.

De Costa’s project, “A Robotic Cat for Examining Camera Clarity and Privacy in Human–Robot Interaction,” focuses on a robotic cat called BARC (the Bioinspired Automated Robotic Cat). BARC is equipped with camera-based facial detection, expressive behaviors, and pre-recorded sounds meant to simulate a household cat. The project studied conceptions of privacy, finding that equipping BARC with a lower quality camera lessened how surveilled the participants felt, without compromising sociability or engagement.

De Costa worked on her project as a member of George Mason’s Human-Agent Collaboration Lab, led by psychology professor Eileen Roesler, which studies human-robot and human-AI interaction. De Costa is very focused on maintaining privacy while keeping the benefits of human-robot collaboration.

“Robotics is advancing at an extraordinary pace, often without full consideration of the people who ultimately interact with these technologies. Being given the opportunity to raise important questions about human autonomy, privacy, and ethics in a government space, particularly at the Capitol in Richmond, was incredibly meaningful to me,” she said.

Senior Emily Keung, a chemistry major with a biochemistry concentration and member of George Mason's Nanoelectronics Research Group, presented her project “2D Diselenide Nanomaterials as Emerging VOC-Adsorbing Platforms for Low-Emission Cosmetic Technologies.” The project found that certain 2D materials could reduce Volatile Organic Compounds (VOCs) in consumer goods such as hair spray or dry shampoo.

VOCs contribute to air pollution and may irritate sensitive groups. Long-term exposure to certain VOCs can also cause serious health issues, making Keung’s research particularly important.

“It was especially meaningful to discuss my research with attendees from outside the university, including policymakers and researchers, and to see genuine interest in how undergraduate research can intersect with public health and materials science,” she said.

She credits her experience at the Nanoelectronics Research Lab, under the guidance of Ethan Ahn, an associate professor in the Department of Electrical and Computer Engineering, with teaching her the skills needed to present her work confidently. 

Honors College student and neuroscience major Sofie Strompf’s research, under her mentors Lance Liotta and Marissa Howard at George Mason's Center for Applied Proteomics and Molecular Medicine, focused on cancer cells’ survivability tactics.  

Her project, titled “Extracellular Vesicle Export of Activated Tumor Suppressor Proteins Following Mitophagy Induction,” found that cancer cells remove damaged organelles and an essential tumor suppressor protein called p53, which allows the cells to evade the body's cancer-suppression mechanisms.

As a senior, Strompf has had several opportunities to present her research over the past four years, including at the National Conference on Undergraduate Research (NCUR) 2024 and 2025, with grants from OSCAR’s Undergraduate Student Travel Fund. She said attending NURVa was particularly meaningful for her this year, as her state delegate, Gretchen Bulova, was able to attend and see her work.

“I was honored to have the opportunity to present to my delegate, especially as a representative of Mason," Strompf said. “I think I nearly cried when she told me that she was impressed with my work and complimented my research communication skills.” 

After she graduates, Strompf plans on pursuing a PhD in neurodegenerative diseases.
