Research Interests

  • Theoretical particle physics with focus on collider phenomenology
  • Multi-loop calculus, differential reduction, dispersion relations, functional equations
  • Precision tests of the Standard Model (SM), determination of fundamental parameters
  • Light-hadron production , jet multiplicities, determination of fragmentation functions
  • Heavy-flavor production, General-Mass Variable-Flavor-Number Scheme
  • Non-relativistic effective field theories and applications to positronium (NRQED), heavy quarkonia (NRQCD factorization), and top-quark threshold dynamics (potential NRQCD)
  • Higgs boson production and decay
  • Decoupling theorems, low-energy theorems
  • Renormalization group analyses and vacuum stability
  • Renormalization in the presence of unstable particles and flavor mixing
  • Physics beyond the SM, models with supersymmetry, two Higgs doublets, Majorana neutrinos
  • Scattering amplitudes, form factors, color-kinematic duality
  • QCD applications to cosmic rays
  • Etc.
