About Me

I am a Ph.D. student in the EECS department at MIT, specifically CSAIL, where I am fortunate to be advised by Srini Devadas. Previously, I earned my bachelor’s degree (B.S.) in Computer Engineering from UC San Diego, where I am fortunate to conduct research under the supervision of Nadia Heninger.

I am broadly interested in applied cryptography. I construct efficient cryptographic tools to enhance the security and privacy of everyone.
