About

I am an Assistant Professor in the Computer Science department at Purdue University.

Before joining Purdue, I was a postdoc in the CIS Lab at NTT Research, where I worked under the wonderful mentorship of Sanjam Garg. I received my PhD from Johns Hopkins University in 2022, where I was extremely fortunate to be advised by Abhishek Jain.

My research interests are in cryptography and in related areas of security and theoretical computer science.

I am looking for motivated students to join me! If you are interested, please feel free to email me or stop by my office.
