I am a computer science PhD
student at CMU, advised by Heather Miller
. I am supported by an NDSEG Fellowship
sponsored by the US Office of Naval Research
My current research focuses on tools for building decentralized systems, including conflict-free replicated data types and secure group messaging protocols. Previously, I studied error-correcting code algorithms and algebraic number theory.
