Hello! My name is Emin, and I am a second-year PhD student in the Computer Science Department at Carnegie Mellon University, where I am a member of the Foundations of the Cooperative AI Lab (FOCAL). I am fortunate to be advised by Vincent Conitzer and to be supported (in part) by the Cooperative AI PhD Fellowship.
My research lies in the intersection of artificial intelligence and theoretical computer science. In particular, I use tools from algorithmic game theory and computational social choice to achieve cooperation in multi-agent settings where the number of agents may be ex ante unclear.
Prior to CMU, I graduated summa cum laude from Harvard University, receiving a joint degree (A.B.) in Chemistry and Physics and Mathematics, with a secondary in Neuroscience, and a concurrent masters (S.M.) in Computer Science. While at Harvard, I had the privilege of being mentored by Ariel Procaccia.
I am originally from 🐈 Istanbul 🐈, where I spent most of life. In my free time I like cooking, hiking, and watching Turkish soap operas at 3x speed.
