I am a Senior Research Scientist interested in the trace gas fluxes from various ecosystems, including peatlands and agricultural systems, especially bioenergy crops and the associated land-use change and have worked on projects in the Arctic, Sub-Antarctic and Tropics as well as temperate ecosystems. My main research focuses on measuring and interpreting biosphere-atmosphere-exchange fluxes of trace gases such as greenhouse gases (CO2, N2O, CH4), NO and ozone depleting gases (methyl halides and volatile organic compounds - VOCs) and the cycling of carbon and nitrogen in ecosystems. My work also involves using gas chromatography (GC-ECD/FID/MS), and new technologies such as quantum cascade laser (QCL), cavity ring-down laser and ion chromatography (IC) as well as infrared analysers for measuring NO.
Current research focuses on nitrogen use efficiency of rice cropping systems in India and greenhouse gas fluxes from oil palm plantations in Malaysia and Indonesia focusing on sustainability issues and restoration options.
I am the Laboratory Manager for the Gas Chromatography Laboratory, the key facility for trace gas analysis at CEH Edinburgh which involves managing and mentoring junior staff.
