I am an Assistant Professor in the Department of Computer Science at Rutgers University. I am interested in various aspects of cryptography and its intersections with formal verification and hardware acceleration.

Previously, I was a researcher at Algorand. Before that, I was a postdoctoral researcher at University of Maryland, hosted by Prof. Jonathan Katz and Prof. Xiaodi Wu. I obtained my Ph.D. at Cornell University advised by Prof. Elaine Shi.

I am looking for self-motivated students. If you are interested in my research, please reach out!
