I am currently an Assistant Professor at the University of the Faroe Islands. In October 2022, I received my PhD (summa cum laude) from TU Dresden (Germany), where I worked on various aspects of interacting quantum field theories which realise scale invariance, primarily pertaining to quantum phase transitions in fermionic systems, but also in part to asymptotically safe quantum gravity. I continued as a PostDoc at the University of Southern Denmark in Odense, where I had a Walter Benjamin Postdoctoral Fellowship of the German Research Foundation (DFG) between 1st March 2023 and 31st August 2024. Here, I studied various aspects of spontaneous symmetry breaking in interacting quantum field theories. A particular focus was on mechanisms which are realised both in condensed matter physics as well as in quantum gravity, with a view towards unified descriptions of certain phenomena in both high and low energies.

My current research interests concern, broadly speaking, various aspects of quantum field theory. A central point of interest remain interacting scale-invariant quantum field theories, especially as pertaining to critical phenomena that go beyond the Ginzburg-Landau phenomenon. Another point concerns Asymptotically Safe Quantum Gravity, which is arguably the most ambitious example of (proposed) interacting scale invariance in the deep ultraviolet. Here, I am particularly interested in phenomenological consequences of this so-called UV fixed point at more readily observable energies, both in the matter sector as well as (approximate) solutions for the spacetime metric. More recently, I have also been interested in formal aspects of renormalisation group flows, especially non-perturbative flows that preserve symmetries (or at least break fewer symmetries than they usually do), by studying non-standard regularisation schemes.
