* 也许做物理所需要的自信，远非同于寻常，它几乎要求你把对自己的相信当做一种信仰，只有这样才能保证你足够坚强，能够去克服所有的困难。只有这样才能保证你不会因为一时的失意而离开物理。** Theoretical research requires a high level of self-confidence and an unshakable belief that one can be strong enough to conquer the innumerable associated challenges.* (Simplified English translation，thank to Jack)

* “You always create the complicated problems.” said by Prof. Jack Gunion, my Ph.D. advisor.*

* “You are the person who would always like to make history.” commented by Prof. Yuanping Feng, the former Physics head at NUS.*

My Profiles on the inSPIRE; Research Gate; ResearchID; ORCiD; PhDtree

My research mainly focuses on LHC phenomenology and new physics implications, including

- Higgs boson physics beyond the standard model

- Supersymmetry

- Dark matter physics

- Extra dimensions

- Inflation of the early universe

I am also interested in Higgs triplet neutrino physics.
