Energy transport and conversion, in the form of free electrons, excitons, photons, heat, etc, underpins important natural and industrial processes, such as photosynthesis, lithium-ion batteries, and photovoltaic devices.

​

Their basic steps, such as electrons hopping from one molecule to another, or heat dissipating through layers of molecules, occur on ultrafast timescale and depend on nanoscale interactions.

 

Thus elucidating the transport mechanisms requires relevant spatial and temporal resolution. We aim to address these questions with ultrafast spectroscopies and microscopies.
