I am currently a PhD student in the team of Risk Analytics and Optimization at École Polytechnique Fédérale de Lausanne (EPFL), working with Daniel Kuhn. My research focuses on optimization under uncertainty with applications in economics and mechanism design. Previously, I received a B.Sc. and an M.Sc. in Industrial Engineering from Bilkent University in 2013 and 2015, respectively. My CV can be found here.
