I am a final year PhD student in the Department of Electrical Engineering and Computer Science (EECS) at the Massachusetts Institute of Technology (MIT), where I am very fortunate to be advised by Prof. David Gamarnik. I am affiliated with the Laboratory for Information and Decision Systems (LIDS) and the Institute for Data, Systems, and Society (IDSS). You can find my CV here.

I am thrillled to join the Department of Statistics at Columbia University as a Distinguished Postdoctoral Fellow in Fall 2022.

Research Interests

My research revolves around problems in high-dimensional statistics, theory of machine learning, and applied probability with an emphasis on computational aspects. In particular, I would like to understand the fundamental computational limits of such problems by studying the regimes of apparent hardness where efficient algorithms cease to exist. This is often guided by the insights provided by statistical physics and spin glass theory.

Other Biographical Notes

I earned my B.S. degree with highest honors (summa cum laude) in electrical and electronics engineering from Bogaziçi University, Istanbul, Turkey in 2014; and my M.S. degree in EECS from MIT in 2017. I did experimental research on magnetic resonance imaging (MRI) for my Master's thesis. Part of my thesis work appeared in the 24th Annual Meeting of International Society for Magnetic Resonance in Medicine (ISMRM), Singapore, 2016; and received a summa cum laude award (top 5% of all submitted works). Slides of my talk is available here.

I am a proud graduate of Ankara Science High School (AFL), class of 2010.
