Summary of Expertise

Theoretical chemistry, materials chemistry, solar energy conversion, electronic structure, optical and catalytic properties of transition metal oxides and interfaces

Research Interests

My research interests focus on developing and employing computational physics/chemistry methods to solve problems related to energy applications, for example to understand and predict materials for photovoltaic, artificial photosynthesis (water splitting and CO2 reduction), and fuel cell applications. Specifically we are currently interested in: 1) Optical properties – study light absorption and excitonic effects for complex semiconducting oxides and low dimensional materials based on many body perturbation theory (GW-BSE), with a method avoiding explicit empty states, storage and inversion of dielectric matrix; 2) Doped metal oxides for solar-to-fuel conversion – study effects of dopant and structural modifications on carrier transport properties of metal oxides from first principles, especially concerning the presence of strong electron-phonon interactions; 3) Complex solid/liquid interfaces – study charge transfer and catalytic properties at solid/liquid interfaces by using implicit and explicit solvents. The key is to tightly connect theoretical and computational predictions with experimental studies, by identifying important theoretical questions whose answers will eventually provide guidance to experiments and suggestions for new materials/architecture design with superior functionalities.
