I joined the Computer Science Department at NJIT in August 2023. I received my B.S. cum laude, M.S. and Ph.D. from UC Irvine.

My group (Redoubt Lab) builds practical solutions to real-world challenges in mobile and cloud computing. Our research spans the areas of operating systems, mobile computing, security and privacy. Specifically, we study the security and privacy implications of emerging technologies such as mobile apps, I/O devices, Artificial Intelligence, and Internet of Things. We build systems to address these challenges, and evaluate them in the real world.

prospective students

I am always looking for self-motivated students who enjoy building systems. If you are interested, please email me with your CV. USE THIS FLOWCHART TO SEE IF YOU ARE A GOOD FIT.
