​​​​Andy obtained his PhD at the University of Bristol studying polymer chemistry and dynamic light scattering. He has been at RAL since June 2000 applying laser microscopy techniques to scientific fields including colloid science, aerosol physics, the life sciences and the application of optical tweezers to wider STFC facility projects. His specific interests are in (i) aerosol chemistry and light scattering properties (ii) surfactant and emulsion behaviour (iii) Raman spectroscopy combined with optical trapping for biological applications, and (iv) combination of optical trapping with imaging techniques suc as confocal, FLIM and TIF microscopy. He is author and co-author on over 50 publications.​
