Research in the Grumstrup group operates at the intersection of materials science and advanced spectroscopy, where we aim to address challenges associated with next-generation photovoltaic materials, nanoscale electronics, and heterogeneous catalysis. We are particularly interested in photochemistry and transport processes that occur on length scales between 10 nm and 10 um, where defects, proximity to surfaces, interfacial regions, and changes in morphology are critical determiners of functionality. To characterize this “mesoscale” region, we develop and utilize nonlinear optical microscopies with femtosecond (~10(-15) second) temporal resolution and sub-micron (10(-6) meter) spatial resolution that allow us to watch non-equilibrium dynamics as they evolve in both space and time. We ultimately seek to understand fundamental questions of material functionality: How does charge separation occur in bulk heterojunction solar cells? Where are the active sites on nanostructured catalysts? How does electron mobility change at the interface of two material domains? Questions like these guide our group as we tackle problems in materials science, interfacial chemistry, nanoscience, and optics.
