Research statement
I am a high energy physicist and collider theorist. My primary research focuses on understanding the origin of tiny, nonzero neutrino masses and tests of neutrino mass models (Seesaw models) at collider experiments, such as the Large Hadron Collider. This includes extended gauge sectors (LR-Symmetric, GUT models), scalar sectors (SU(2)L doublets and triplets), and fermionic sectors (SU(2)L singlets and triplets). I have a particular interest in collider signatures involving initial-state electroweak vector bosons (vector boson fusion/scattering) and the impact of (resummed) QCD corrections on (new physics) collider processes. This includes resummation in the context of perturbative QCD and SCET.
