Welcome!

Hello! I am a current PhD student studying under Professor Taeho Jung in the Department of Computer Science and Engineering at the University of Notre Dame. I am a part of the Data Security and Privacy Lab (DSP-Lab). I am currently a member of the Computer Science Grad Student Board. Previously, I have completed two years interning at MITRE as a Cybersecurity Graduate Intern and two years interning at Raytheon as a Software Development Intern.

Previously, I completed my undergraduate degrees, a B.S in Computer Science and B.S in Mathematics at Georgetown University, graduating in 2023.

My research focuses on cryptography, particularly the execution of Privacy Enhancing Cryptography (PEC) using Fully Homomorphic Encryption. Recently, I have focused on how PECs can be applied to LLMs and the agentic process.
