My name is Gregory Rosenthal. I am a fourth-year MSc/PhD student at the University of Toronto, where I am fortunate to be co-advised by Benjamin Rossman and Henry Yuen. Previously I was a math major and computer science minor at Cornell. My research interests are in computational complexity theory and related areas, including quantum circuit complexity and boolean function analysis.

Visits

I was fortunate to attend much of the Fall 2018 program Lower Bounds in Computational Complexity at the Simons Institute for the Theory of Computing.

Other Activities

From Jan. 2018 to July 2019 I coordinated the weekly Cookiebreak for grad students in the department. I play cello in an orchestra on campus, and as an undergrad I played in the Cornell Orchestras and also conducted the Cornell Eastern Music Ensemble. In Summer 2013 and Summer 2014 I was a resident assistant at AwesomeMath Summer Program (AMSP).
