Bora Yongacoglu

I am an applied mathematician who specializes in multi-agent systems and game theory.

I received my PhD from Queen’s University under the supervision of Serdar Yüksel and Gürdal Arslan (University of Hawaii). After Queen’s, I had the pleasure of doing postdoctoral fellowships at the University of Toronto, where I was mentored by Lacra Pavel, and at Mila, where I was mentored by Gauthier Gidel.

Current Interests:

• learning in games
• multi-agent reinforcement learning
• large-scale auctions
• mechanism design for online auctions
