I am a postdoctoral researcher in CMU Theory of Computation group . My gracious hosts are Venkat Gruswami and Pravesh Kothari .

Before September 2019, I was used to discuss randomized numerics with Felipe Cucker
at Berlin, where we were hosted by
Peter Bürgisser .

I was also very fortunate to learn some very cool things in real algebraic and tropical geometry from Cynthia Vinzant .

I have learned high dimensional probability and convex geometry from Grigoris Paouris , toric geometry and computational algebraic geometry from J. Maurice Rojas . Maurice and Grigoris approved my PhD dissertation on August 2016.

I am originally from Denizli , Turkey . I still hope that one day, Turkish people will not be scared to dissent.

My research interests revolve around real algebraic geometry, discrete and convex geometry, optimization, high dimensional phenomena (such as concentration of measure), and connections of these topics with algorithms and complexity theory.

A statement of my research interests is here , and an informal summary of my writings is here .
