Research Interests

My research interests right now concentrates on physics related to dark matter and the Higgs particle. Together with my collaborators, I build models to understand the properties of dark matter and also try to probe dark matter with with these possible new properties. I am also trying to understand the possible new physics contributions to the Higgs decay pattern found in the LHC, which might be different from the prediction of the Standard Model.
