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).
