Research Interests

My research interests are precision measurements of the Cabibbo-Kobayashi-Maskawa (CKM) matrix elements aimed for understanding the source of asymmetry between matter and anti-matter, testing the Standard Model, and discovering New Physics beyond the Standard Model. The Big Bang produced matter and anti-matter in equal numbers. Experiments revealed that for every fundamental particle there exists an anti-particle. However, observations indicate that we live in a universe of matter. There must be some other undiscovered phenomenon that makes matter and anti-matter behave differently. Its source may lie in the properties of Dark Matter, Dark Energy, Supersymmetry Particles, Gravitons, or Extra Dimensions.
