About Me

I study cryptography and consensus algorithms, focusing on security of consensus protocols under different trust models and network conditions.

I am a graduating computer science PhD student at University of Maryland College Park, advised by prof. Jonathan Katz.

Update (Spring 2023): I’m excited to be joining the CS department at Reed College as an assistant professor, starting Fall 2023.
