#### Research interests

I am interested in the interplay between analysis, geometry and physics. Broadly speaking one could classify my research as geometric analysis and mathematical physics. I develop and apply techniques from analysis, including partial differential equations, and metric geometry to problems in (semi-)Riemannian geometry and mathematical general relativity.

Topics I am interested in include:

- mathematical general relativity
- Einstein equations (vacuum and with matter, in particular, fluids and electromagnetism)
- black holes and naked singularities
- global and asymptotic behavior of solutions

- global Riemannian and Lorentzian geometry (including metric geometry)
- synthetic and analytic approaches for nonsmooth spaces and spacetimes
- causality theory
- analysis and geometry of metric (measure) spaces

- nonlinear wave equations and hyperbolic conservation laws

Apart from pure mathematics and mathematical physics I am also interested in mathematical problems arising in geosciences.
