Summary of Expertise

Theoretical chemistry, materials chemistry, electronic structure, optical excitations, spin dynamics,  two-dimensional materials, electronic transport and catalytic properties of transition metal oxides and interfaces, defect physics, solar energy conversion, quantum information science

Research Interests

My research interests focus on developing and employing advanced theoretical and computational techniques to solve problems related to energy conversion and quantum information science. Specifically we are currently interested in: 1) Optical excitation and spin dynamics – first-principles methodology development on excited-state dynamics for solids and nanostructures, in particular, from many-body perturbation theory with improved numerical efficency and accuracy, and open quantum dynamics based on ab-initio density matrix formalism with environmental couplings; 2) Polaronic transport  – study effect of dopants 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 observations, by identifying important theoretical questions whose answers will eventually provide guidance to experiments and suggestions for new materials/architecture design with superior functionalities.
