I was PostDoc with Amin Coja-Oghlan whose project is founded by the german research council (FOR 2975).  Formerly, my PhD project "Large Discrete Structures: Statistical Inference, Combinatorics and Limits" was supervised by Amin Coja-Oghlan and Yury Person. In 2018, I achieved my Master of Science in Mathematics at Goethe-University Frankfurt. Before, I achieved my Bachelor's degree at Goethe-University Frankfurt and passed the first State examination in 2016 for the teacher profession at upper secondary school with the training subjects Mathematics and Computer Sciences.

My research interest centers around combinatorial random matrices and their applications.  I am particularly interested in spectral analysis/algorithm of matrices that arise from random graphs and its applications in disordered systems, CSP, and coloring problem.

I was a Ph. D. student under the supervision of Prof. Dr Amin Coja-Oghlan from TU Dortmund.  I was also a research assistant at TU-Dortmund and supported by the following grant: DFG CO 646-4 Random graphs: cores, colouring and contagion, 2018-21 joint initiative with Mihyun Kan, TU Graz (funded by FWF I3747). For my research areas, I am interested in constraint satisfaction problems, random graphs and analytic combinatorics.
