Marco Jiralerspong

Hi! I'm a third-year PhD student in computer science (fast-tracked from masters) at Université de Montréal/Mila supervised by Gauthier Gidel and supported by NSERC.

Previously, I did my undergrad at McGill where I majored in computer science with minors in mathematics and economics. I also interned as a software engineer at Google, Amazon Robotics and Squarepoint Capital.

I am currently working on soft variants of reinforcement learning and potential applications to multi-agent problems. In the past, I've worked on generative models and their evaluation.

Generally, any topic that bridges computer science, economics and mathematics will be of interest!
