Sait Cakmak

I am a Ph.D. student in Operations Research at Georgia Tech. Before joining Georgia Tech, I studied Industrial Engineering and Economics at Koç University, Turkey.

My research focuses on optimization of black-box or simulation-based objectives, using zeroth or first order information. In particular, I studied risk averse optimization of such objectives, where risk aversion is achieved by optimizing a risk measure of the objective, calculated over the unknown environmental variables. I have used tools from stochastic derivative estimation, stochastic approximation, Bayesian optimization and Gaussian processes, among others. I have been fortunate enough to be advised by Dr. Enlu Zhou, and collaborated extensively with Dr. Peter Frazier of Cornell University.

In my free time, I enjoy woodworking, hiking and camping. I recently gained an interest in robotics, which I am using to build a toy for my cat, Python!
