About Me
Who I am: I am a mathematician interested in problems in discrete geometry and the theory of quadratic forms, with emphasis on spectral methods for chromatic numbers and packing problems, as well as geometric and algebraic aspects of (integral) lattices. Currently I am a postdoctoral researcher in the group of Frank Vallentin at the Universität zu Köln.
I obtained my doctorate degree form the Technische Universität Dortmund with Rudolf Scharlau as my advisor.

Short overview of my research interests:
- Spectral bounds in discrete geometry
- Chromatic numbers of symmetric spaces
- Euclidean lattices and their suitability for the sphere packing, covering and quantizer problem
- Hermitian lattices over totally imaginary quadratic extensions of totally real number fields
- Similarities of Euclidean lattices (and their connection to algebraic structures that lattice is defined over)
- Applications of Euclidean lattices to coding theory
