I am a Math+ Postdoc in the Combinatorics and Graph Theory Group of Tibor Szabó at FU-Berlin and associated with the Interactive Optimization and Learning Laboratory of Sebastian Pokutta at the Zuse Institute Berlin. Previously, I was a visiting fellow at the London School of Economics and Political Science funded by a fellowship of the German Research Foundation (DFG, Grant PA 3513/1-1) and a postdoctoral researcher at TU Ilmenau. I obtained my Ph.D. at Goethe University Frankfurt am Main, where my supervisor was Yury Person.

Research Interests

My research interests are probabilistic and extremal combinatorics, Ramsey theory, and machine learning. I am mostly working on embedding type problems for graphs and usually they involve randomness in one way or the other.
