Research Overview

 

Research has largely focused on developing and then using time-resolved laser methods (on femtosecond and longer time scales) to study a range of phenomena such as radiationless transitions from excited states; rotational diffusion in solutions, membranes and proteins; electron and energy transfer in photosynthetic organisms; electron transfer in organic molecules and in DNA???s, and photo-induced protein folding and unfolding. Protein unfolding under the influence of force has also been extensively studied using Atomic Force Microscopy.

Most recently, a new technique based on the Hadamard transform has been developed for use in time-resolved spectroscopy and most importantly in time-resolved x-ray crystallography.
