I work on theoretical high energy physics and cosmology — the connection between the tiniest elementary particles and the entire universe. My main research interest is cosmic inflation, which describes the origin of the universe. A focus of my research involves extracting information about fundamental particle physics from the properties of inflation.

The great fun of doing research also drives me to explore other areas: gravitational waves, cosmic strings, eternal inflation, dark matter, dark energy, modified gravity, AdS/CFT and computer algebra.

A list of my papers can be found at INSPIRE, or HKUST library. See also the research group of Center for Fundamental Physics for related research at HKUST.
