Quantum Prediction of Advanced Materials

My group’s research deals with the study and design of advanced materials using first-principles computational modeling and simulation. We use quantum mechanics and statistical mechanics to study electronic structure, interatomic bonding and microscopic kinetic processes in modern high-performance materials. Our group focuses on two key areas: (i) materials for generating, storing and converting energy, such as on-board hydrogen storage, thermoelectrics, electrochemical supercapacitors, and advanced nuclear fuels, (ii) theory of bulk and surface alloys, including nanoscale self-assembly and pattern formation. Our research is funded by NSF, DOE, and SRC-MARCO.
