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.

Research Interests

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

I am also interested in Higgs triplet neutrino physics.
