I’m a computer science PhD student at the University of Maryland, in the Cybersecurity Center (MC2) and programming language lab (PLUM). I study distributed systems, programming languages, and cryptography. I’m especially interested in secure p2p networks, like Bitcoin. My advisors are Jonathan Katz, Elaine Shi, and Michael Hicks.
I am a member of the zerocash project.
