Research:

My current research interest lies in searching for signature of beyond Standard Model (SM) physics in low energy precision experiments. In particular, the theory with supersymmetry and extra dimensions solves the hierarchy problem in an elegant way. Searching for their signature in experiments and finding appropriate observables to distinguish them is my main interest.

My past research was related to neutrino physics and Grand Unification Theory (GUT) model building. Together with X. Ji and R. Mohapatra, we constructed SO(10) GUT model with lopsided structure which successfully fits all the fermion masses and mixing angles.
