Professional Profile

2009-

Lecturer in Chemistry, Monash University, Australia.

2006-2008

Centenary Research Fellow, University of Melbourne, Australia.

2003-2005

Postdoctoral Fellow, Katholieke Universiteit Leuven, Belgium, in the De Schryver – Van der Auweraer – Hofkens group.

2002

Postdoctoral Fellow, Max Planck Institute for Radiation Chemistry, Germany, in the Braslavsky group.

1997-2001

PhD, University of Melbourne in the Ghiggino group.

Research Interests

Single molecule spectroscopy, time resolved fluorescence, energy transfer (FRET), energy transfer, 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.
