Research

My research field is in elementary particle physics theory, focusing on high-energy collider physics and in connection to astro-particle physics and cosmology. I formulate theoretical models of elementay particles and their interactions, and develop the strategies to test the theory by experiments and observations. This research direction, bridging the abstract theory and experimental observation, is the field of Phenomenology.

The fundamental questions I have been contemplating on from theory, and seeking for an answer in experiments, include

  • The origin of mass for elementary particles
  • Fundamental forces and their unification
  • Symmetries and their breakdown: Gauge-, Super-symmetry, CP Violation etc.
  • Nature of particle Dark Matter
  • Property of Space-time

The experiments at the Large Hadron Collider (LHC) are collecting a staggering amount of data at the unprecedented energy and luminosity frontier. The discovery of neutrino mass and oscillation has stimulated the theoretical development for further understanding of many fundamental aspects in particle physics. Experiments and observation in cosmology and astroparticle physics have deeply reached the regime to probe dark matter hypothesis associated with the weak scale new physics. Phenomenology is thus in a golden era and I am thrilled to be part of the team at the dawn of the major discoveries associated with the above questions at the shortest distances of about 10-10 nm.
