Areas of Interest
Our research focuses on theoretical particle physics, with particular emphasis on:
Higher-order calculations in the Standard Model (SM) and Beyond the Standard Model (BSM) physics.
Dark matter phenomenology and direct detection.
Astroparticle physics.
Related topics in particle phenomenology where precision theoretical calculations can provide significant insights.
Experience
Before joining the Institute of Physics (IOP) in 2017, I held postdoctoral research positions at the Laboratoire de Physique Théorique (LPT), Orsay, and the University of Würzburg. I was also a visiting researcher at the Harish-Chandra Research Institute (HRI).
