Research Overview

My research is concerned with the study of molecular photophysics and photochemistry and the development and application of fluorescence spectroscopy and imaging. I am particularly interested in the application of fluorescence methods to biomolecular systems. Current projects in my group include:

  • Probing DNA conformation and DNA-enzyme interactions, using time-resolved fluorescence spectroscopy.
  • Quantitative spatial mapping of mixing, temperature, pH and other measurands in microfluidic (lab-on-a-chip) systems, using fluorescence lifetime imaging microscopy (FLIM).
  • Ultrasensitive fluorescence detection of surface-bound protein, e.g. protein contamination on surgical instruments.
  • Developing advanced photonics for the study of biological systems.
  • Investigating the photoisomerisation of azo dyes, using NMR spectroscopy with in situ laser irradiation.
