• High resolution absorption and emission spectroscopy of molecules to study vibrational energy redistribution and develop models of energy flow beyond
Fermi%27s_Golden_Rule. • Dynamics of fast-folding proteins to make the connection between experiment and physics-based computer simulations of
protein folding. • FreI (fast relaxation imaging) that combines
fluorescence microscopy and fast
temperature jump or osmotic
pressure jump to study protein dynamics inside living cells and living animals. • A sub-microsecond pressure jump technique to study fast protein refolding and help guide computer simulations (
molecular dynamics) for how proteins fold. • With Martina Havenith, kinetic terahertz absorption spectroscopy elucidating the role of long-range interactions of water with biomolecules. • Two-state dynamics recorded on glass surfaces using time-resolved
scanning tunneling microscopy, to measure the size and heterogeneous dynamics of cooperatively rearranging regions on a glass. • SMA-STM (single molecule absorption detected by
scanning tunneling microscopy), a technique that can image excited state orbitals of nanostructures with sub-nanometer position resolution and sub-picosecond time resolution. • With
Stephen Boppart, non-linear interferometric vibrational imaging which produces easy-to-read, color-coded images of tissue, outlining clear tumor boundaries with more than 99% confidence. • Computational and theoretical work in the area of quantum energy flow, quantum computation, and quantum information, as well as fundamental transport theory. • Animal behavior studied by using physics-constrained AI analysis. ==Awards==
