One focus of my work is on a particular relation between differential geometry and physics: geometric supersymmetry. This expression describes the various connections between differential geometry and supersymmetry. Undoubtedly, representation theory and spin geometry are two important mathematical fields within this topic.

In this context, I am interested in (pseudo)-Riemannian geometry, geometric analysis, combinatorics, geometric algebras, geometry of supermanifolds, deformation of geometric structures, Yang-Mills theory, supergravity, string theory, and deformation quantization.

In general, my research interest is on the various relations between mathematics on the one hand and natural sciences, engineering and economics on the other hand.

Moreover, I like to apply mathematics to problems and questions that arise from practical applications; for example electrical engineering, automation engineering, finance and markets, or economics in general. So feel free to contact me if you are in need of advice for your mathematical problem.
