| Areas of expertise | The research in my group concentrates on the use of pulsed and cw diode lasers for studying chemical reactivity, atmospheric chemistry, methods of trace gas detection, optical properties of aerosol particles, the chemical composition of plasmas, and molecular spectroscopy and photochemistry. Techniques such as multiphoton ionisation and cavity ring-down spectroscopy provide the necessary sensitivity for these experiments. In addition, we use computational methods for ab initio electronic structure theory and molecular dynamics to aid the interpretation of experimental measurements. My group is part of the EPSRC-funded Bristol - Oxford Programme Grant New Horizons in Chemical and Photochemical Dynamics, and we also collaborate with Prof Gus Hancock, Dr Grant Ritchie and Dr Robert Peverall of the University of Oxford in the use of cavity enhanced spectroscopy methods in atmospheric, medical, plasma and analytical chemistry. |
