Research Profile

My research expertise lies in the field of partial differential equations on spaces with singular geometry. In particular I currently work on topics in spectral geometry, parabolic Schauder theory with applications to non-linear geometric evolution equations, in the setup of singular spaces. One fundamental aspect of my research is the microlocal approach to the elliptic theory of edge degenerate differential operators. The analysis of regular-singular Sturm-Liouville operators also takes a central place within my research interests. One other activity area results from the ansatz to define the quantum field theoretical path integral als the regularized limit of its discrete realisation, using tools from discrete geometry and approximation theory.

• Spectral geometry on singular spaces, spectral invariants
• Boundary value problems for degenerate elliptic operators
• Geometric flows, Ricci and Yamabe problems, fourth order equations
• Regular singular Sturm Liouville operators, zeta determinants
• Topological quantum field theory, discrete geometry

My research results are specifically concerned with the following topics

• Analytic Torsion on Singular Manifolds
• Refined Analytic Torsion on Manifolds with Boundary
• Parabolic Schauder Theory, Geometric Flows
• Edge Degenerate Boundary Value Problems
• Regular Singular Sturm-Liouville Operators
• Discrete Quantum Field Theory
