Welcome

Our group performs time-resolved optical studies of excited-state dynamics in materials for applications in energy conversion and energy storage. We are associated with the Department of Chemical & Environmental Engineering and the Energy Sciences Institute at Yale University. We are always looking for prospective PhD students with backgrounds in Engineering, Materials Science, Physics, Chemistry. Students interested in applying could reach out to Prof. Guo via email.
