Areas of research:
I'm working mostly on non-perturbative renormalisation group flows, with a focus on quantum gravity in the Asymptotic Safety scenario. This scenario stipulates that gravity is renormalisable by an interacting fixed point in the ultraviolet. My research tries to resolve the momentum dependence of vertices which is essential in the calculation of physical observables like scattering cross sections.
