Biographical Outline

I received a PhD from the Hong Kong Polytechnic University in 2012 with a thesis in ferroelectrics. I also worked on other subjects such as high temperature superconductors and polymer dynamics as well as open quantum systems. Shortly after finishing my PhD, I visited and joined Dr. K. Wakabyashi's group in National Institute for Materials Science (NIMS) in Tsukuba, Japan. There I was awarded a two-year fellowship by the Japan Society for the Promotion of Science (JSPS) to study the electronic and transport properties of atomic layers such as graphene. I took my current position in Feb. 2016. 

Research Interests

My current effort is focused on plasmonics and nanoelectrochanical systems (NEMS), while I also keep a close eye on the development in the field of hgih Tc superconductors and glassy dynamics in atomic liquids.
