Research Interests

I am a particle theorist and collider phenomenologist. My primary research focuses on origin of tiny but nonzero neutrino masses and tests of neutrino mass-generating mechanisms (Seesaw models) at current and future colliders. 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 particular interest on collider signatures involving initial-state vector bosons (vector boson fusion) as well as final-state scalar and vector bosons (h, Z, W).
