Ginsberg's group devises new ultrafast electron- and optical-microscopy modalities to watch charge, energy, and structural dynamics in soft and hybrid materials (organic semiconductors, perovskites, biomolecular assemblies) on their native nanometer/femtosecond scales. The lab is actively recruiting postdocs to extend these methods toward operando imaging of energy materials.

King develops polarization- and time-resolved PEEM together with ultrafast (scanning) transmission electron microscopy to image charge-carrier, exciton, and phonon dynamics with nanoscale (down to ~25 nm) spatial resolution at buried interfaces and in 2D materials such as black phosphorus. Her group is now retrofitting a high-throughput PEEM, in collaboration with the Kasthuri lab, for whole-brain connectomics -- an unpreferred/borderline inclusion since the core program is materials-science imaging rather than biosensing, but one that is directly extending resolution-pushing microscopy into neuroscience.
