- Fellowship in 2017 at Columbia University
Sam received his PhD in theoretical physics from Hong Kong University of Science and Technology where he worked with Prof. Henry Tye, who is a pioneering string cosmologist. He was a Croucher fellow at Columbia University from 2017 to 2019. He is now a postdoc at University of Pennsylvania.
Sam is interested in cosmology and particle theory. He conducts research in revealing the early cosmological history to infer the origin and fundamental nature of our universe. In particular, inflationary models, quantum nature of the early universe and black hole physics. He also studies baryon/lepton number violation of the standard model to understand the origin of matter anti-matter asymmetry.
