Biography

I have a Master's degree in Applied Physics and Mathematics from the Norwegian University of Science and Technology (NTNU), which I finalized with a thesis on Higgs-Mediated Neutrino Pair Production in the Next-to-Minimal Supersymmetric Standard Model. During my master's degree, I spend a one-year exchange at the University of Bologna, where I took courses from the master's program in Theoretical Physics. 

Research

My research revolves around theoretical modeling of scattering and bound motion of black holes, which are sources of gravitational waves, the latter being detected by the LIGO-Virgo-KAGRA collaboration. I use the tools of effective quantum field theories and scattering amplitudes, and my current focus is to model tidal deformations of the black holes.
