Hey there,

I am a PhD candidate from the Department of Computer Science at New Jersey Institute of Technology (NJIT). My doctoral advisor is Professor Zhihao (Zephyr) Yao. I am a member of the Redoubt Lab research group.

I received my B.S. cum laude in Computer Science from the University of Arizona in 2018 and M.S. in Software Engineering from NJIT in 2023.

My research focuses on the security and privacy aspects of artificial intelligence and mobile systems.
