In particular, I am interested in: •Discovering the fundamental photophysical properties of new materials at the single molecule level. •Understanding how energy is transported around in multi-chromophoric dye molecules, polymer chains and nanoparticles •Using SM techniques to address biophysical problems such as protein folding, aggregation and conformational change.
