His research interest includes hot-carrier utilization strategies (e.g., slowed hot-carrier cooling in metal-halide perovskite systems and multiple exciton generation in quantum dots) in reach the ultimate thermodynamic limits of solar energy conversion. Interest also include controlling the optical and electrical properties of QDs, QD arrays, and other reduced dimensional systems for solar energy transduction including photochemical energy conversion. Finally, he is also developing ultrafast spectroscopic probes of interfacial carrier dynamics important for energy conversion architectures.
