I am a postdoc at the Korteweg-de Vries Institute for Mathematics at the Universiteit van Amsterdam, mentored by Ross Kang. Before that, I was a PhD student in the research group Geometric, Algebraic and Probabilistic Combinatorics at UPC Barcelona under the supervision of Oriol Serra and Juanjo Rué. I have also spent a year at TU Dortmund working as a research assistant in Christian Sohler's group as part of the ERC starting grant "Sublinear Algorithms for the Analysis of Very Large Graphs". Both my Master's and Bachelor's degree were obtained at Freie Universität in Berlin. I am broadly interested in all areas of extremal and probabilistic combinatorics, with a special focus on combinatorial problems that have a connection to topics in additive number theory.
