Sobhan's Blog ðŸŽ²

Hi, I'm Sobhan.

I'm doing a PhD at MIT advised by Gabriele Farina working on computational game theory. I'm interested in computational tools for finding equilibriums of large games.

Previously I did an MSc and BSc at Université de Montréal . My MSc was advised by Emma Frejinger and Pierre-Luc Bacon . I was affiliated with Mila and CIRRELT where I worked on problems adjecent to reinforcement learning (RL), regularization (entropy), and traffic modeling.

You can reach me via email at first two characters of my first and last name + @mit.edu You can also find me on github @SobhanMP where I sometimes contribute to open source software.
