Welcome to the ExSiTE Lab (Experiments and Simulations in Thermal Engineering) at UVA, and research homepage for Professor Patrick E. Hopkins. Our group’s interests are in energy transport and coupled photonic interactions with condensed matter, soft materials, liquids, vapors, plasmas and their interfaces. We use various optical thermometry-based experiments to measure the thermal conductivity, thermal boundary conductance, thermal accommodation, strain propagation and sound speed, optical properties, and electron, phonon, vibrational and polaritonic scattering mechanisms in a wide array of bulk materials and nanosystems.
