I'm a PhD student in the group Algorithmic Algebra at the Institut für Mathematik of TU Berlin. My advisor is Prof. Dr. Peter Bürgisser and I'm part of his ERC Advanced Grant Project COCAN: Complexity and Condition in Algebra and Numerics.
Moreover, I'm a Phase II student at Berlin Mathematical School, a joint graduate school of the three Berlin universities.
Besides mathematics, I enjoy coffee, bouldering and listening to music.
Generally, I'm interested in Commutative Algebra, Algebraic Geometry, Representation Theory, their interactions such as in Geometric Invariant Theory and their applications, e.g. Cryptography.
My PhD thesis- and ERC Project-research lie in the area of Computational Invariant Theory. This fascinating branch of mathematics combines many different fields like Geometric Invariant Theory, Symplectic Geometry, Discrete Geometry and Optimization.
