I am an AI Researcher at MIT Lincoln Lab. I earned my Ph.D. in Information Sciences and Technology at The Pennsylvania State University under the guidance of Dr. Dongwon Lee at the PIKE Lab in August 2023. While at Penn State, I was a Button-Waller Fellow, an NSF Scholarship for Service Scholar, and an Alfred P. Sloan Scholar. I earned a B.S. in Mathematics, with a minor in Statistics at University of Maryland Baltimore County (UMBC) in May 2018. While at UMBC, I was a McNair scholar and a member of Pi Mu Epsilon (the Mathematical Honorary Society). My research interests are: Artificial Intelligence, Machine Learning, and Data mining in the application domain of Cybersecurity. Specifically, I am interested in:
- NLP (Natural Language Processing)
- NLG (Natural Language Generation), such as Large Language Models (LLMs)
- Adversarial Robustness & Adversarial Machine Learning
- TDA (Topological Data Analysis)
