Research Interests

Photophysics and photochemistry, time-resolved fluorescence spectroscopy, fluorescence lifetime imaging microscopy, DNA conformation and interactions, microfluidics

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.
