Researcher interests: applications of ultrafast spectroscopy to condensed phase photochemistry and photobiology. State of the art femtosecond lasers are constructed in house, and used to develop spectroscopic methods for following chemical dynamics in real time. Small model systems are investigated to appreciate the effects of condensed surroundings on photoinduced dynamics. Similar methods are also applied to study photo-reactive systems of intrinsic functional importance such as photosynthetic proteins, or more recently exciton dynamics in semiconductor nano-crystals and in novel photovoltaic materials. Some major themes of interest are detailed below.
