I am a second year Ph.D. student in the David R. Cheriton School of Computer Science at University of Waterloo, advised by Kimon Fountoulakis. I am a member of OpAL lab. I work on machine learning and optimization problems over graphs. Previously, I obtained a Master of Mathematics in the Department of Combinatorics & Optimization, where I worked with Ricardo Fukasawa and Laurent Poirrier.
