I am an associate professor in the Physics Department of the National Taiwan Normal University. My research specialty is the theoretical physics of elementary particles and quantum fields, especially the phenomenology of the standard model, extra dimension physics and other beyond standard models.

The following is my current interest and ongoing projects:
It has been a long held belief that the gravitational force is too feeble to have an impact on particle physics at the weak scale. But why is it so weak? The idea is to assume the existence of n compact extra dimension plus 4 noncompact spacetime. All the matters are to live in a three dimensional membrane, called brane, but the gravitational force line can escape into the n extra dimension. Assume that either n is large or the size of the extra dimension is large compared to particle size. For example n=2 and the size is about 0.1mm or n=3 and the size is 10-7 cm. Anyway, the gravity field lines are too spread out that the gravitational force between matters becomes extremely weak, as we observed.
2. Supersymmetry (SUSY), symmetry breaking and Low Energy Phenomenology
Supersymmetry is a beautiful idea that not only cures the "naturalness" problem of the Higgs mechanism in Standard Model and also unifies the physics of bosons and fermions. The latter property render huge predictive power which is only recently discovered. By holomorticity, non-perturbative property of SUSY gauge field theory can be calculated. This could have strong impact on our understanding of symmetry and symmetry breaking property of quantum field thery. Currently we are concentrating on how this predictive power can be used in the discreet symmetry, like CP, in a SUSY gauge field theory. On the other hand, one of the most urgent problems facing SUSY is how to break it as it has to be. Attention has turned to the dynamical symmetry breaking mechanism lately. However the models built so far are still too clumsy to be true. I plan to study the phenomenological implication of SUSY dynamical symmetry breaking and also try to improve on the models realizing this idea.

I maintain an archive for research papers. You have the choice of browsing the abstracts, or downloading LaTeX, or Postscript versions of the papers.
