Kohler Group

DNA Photophysics & Solar Energy Conversion

The Kohler group investigates the photophysical and photochemical dynamics of excited electronic states in the condensed phase. Molecular excited states are prepared ‘instantly’ with femtosecond laser pulses and interrogated as a function of time, using electronic and vibrational spectroscopy. In analogy to microscopy, which provides access to miniscule spatial dimensions, femtosecond laser spectroscopy reveals the temporal evolution of the microscopic world. Current research projects seek to understand how DNA is damaged by UV light, and develop photochemical approaches for harnessing energy from sunlight.
