Research:

My main research focus is fundamental symmetries in nuclear systems, in particular the parity and time-reversal violations. The recent accomplishments by me and my collaborators include a quantitative study of parity violation in two-nucleon systems and the underlying nuclear parity-violating interaction based on effective field theory; and a re-derivation of Schiff theorem -- which strongly affects the interpretation of electric dipole measurements in neutral systems -- in a fully quantum-mechanical fashion. Our current activities, based on these previous work, involve carrying out calculations of parity-violating observables in few-nucleon systems, which the program of Fundamental Neutron Physics Beamline at the Spallation Neutron Source is going to measure; and calculations of electric dipole moments of several nuclei and atoms of great experimental interests, as these measurements/bounds provide stringent constraints of beyond-the-Standard-Model physics and have important implication for cosmology.
