Dr Toby Bell - Researcher Profile

Biography

Toby works in the School of Chemistry at Monash University as a Lecturer

Toby’s research areas of interest are:

•Single molecule spectroscopy, time resolved fluorescence, energy transfer (FRET), 
 annihilation phenomena, photon bunching and photon correlation.
•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.
