Morgan Shirley

I am a PhD student at the University of Toronto Department of Computer Science in the Theory of Computation research group, where I am advised by Toni Pitassi and was previously advised by Ben Rossman. I also have an M.S. degree from Oregon State University, where I was advised by Mike Rosulek. We worked on problems in cryptographic complexity.

From a young age I have been interested in computing. More recently, I have focused my attentions on computational complexity. I am most excited about questions related to communication complexity.
