His research is primarily in the field of long term monitoring of atmospheric chemical composition and radiation, using spectroscopic techniques. He has developed UV/Visible spectrometer systems for the measurement of the stratosphere radicals important in ozone loss chemistry, as well as applying similar techniques to measure halogens in the boundary layer. He has been a co-chair of the global Network for the Detection of Atmospheric Composition Change (NDACC), UV/Visible Work Group. He is also the GCOS Reference Upper Air Network (GRUAN) representative.
