I am a computer science PhD
student at CMU, advised by Heather Miller
. I am supported by an NDSEG Fellowship
from the US DoD.
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.

I play tenor saxophone in CMU's Tartan Wind Ensemble. I can juggle five balls and three of various other objects.
Math is Fun?

Here is a packet of "fun" math problems
, compiled from various sources by a group including William Hoza
, Laura Shou
, Jalex Stark
, Michael Wheeler, and myself. They are designed to be printed double sided and cut in two, so that each problem has a link to its "answer" on the back.
