I am a second year PhD student in Computer Science at Cornell University advised by Ari Juels.
My current research interests are broadly in theoretical and applied cryptography with some emphasis on blockchains.

I completed my undergrad at Purdue, where I majored in Computer Science, Mathematics, and Statistics.
At Purdue, I was advised by Aniket Kate and Elias Bareinboim.

I help organize the Security and Privacy Discussion Group (SecDG) at Cornell.
