I am a third year Ph.D. student in the Department of Computer Science at the University of Toronto, supervised by Chris Maddison and Murat Erdogdu. Previously, I did my M.Sc. degree in the Department of Mathematics and Statistics at McGill University under the supervision of David Stephens. Before that, I did my B.Sc. degree in Honours Mathematics and Computer Science at McGill University.
