About

The research field I am mainly interested in is the search for New Physics (NP) effects in High Energy Physics. My research focus lies on flavor physics and the application and phenomenological implications of Effective Field Theories (EFTs) such as the Standard Model Effective Field Theory (SMEFT) or the Weak Effective Field Theory (WET) valid below the electroweak (EW) scale. I was however also involved in several Standard Model (SM) computations including the observable ε'/ε as well as the computation of non-perturbative contributions to the Bc lifetime in non-relativistic QCD.
