Research in high-energy collider phenomenology and perturbative QFT

My research aims to deepen our understanding of fundamental interactions by testing the Standard Model of particle physics with high precision. One focus is to study the properties of the Higgs boson in detail and to search for subtle deviations from theoretical predictions that could signal new physics. Another is to determine the fundamental parameters of the Standard Model with the highest possible accuracy.

Achieving these goals requires theoretical predictions that go beyond leading-order approximations in perturbation theory. My work currently focuses on computing higher-order radiative corrections, which involve increasingly complex scattering amplitudes with many particles and energy scales. I develop new analytic and numerical techniques to make these computations feasible. This research brings together a broad range of topics: from insights into the mathematical structure of Feynman integrals and scattering amplitudes in QFT to the development of efficient algorithms used in Monte Carlo event generators that describe how particles are produced in collider experiments.
