Richard Schaller

Richard Schaller is Professor in the Department of Chemistry at Northwestern University's Weinberg College of Arts & Sciences, with a joint appointment at Argonne National Laboratory's Center for Nanoscale Materials.

Research investigates quantum confinement effects using ultrafast transient absorption/emission spectroscopy. Focus areas include single exciton relaxation mechanisms, multiple exciton generation/fate, and nanomaterial optical properties. Current projects examine exciton dynamics in semiconductor nanocrystals and carrier multiplication processes.

Research approach combines ultrafast spectroscopy (>100 fs resolution) with nanomaterials synthesis collaborations. Group meetings biweekly; coordinates with synthetic/theoretical groups at Northwestern, Argonne, and external institutions.
