Tom currently leads the Soil Atmospheric Interactions research group at North Wyke. Current research activities relate mostly to greenhouse gas and ammonia emissions from agricultural sources: quantification, understanding processes, model development and development of abatement strategies. Responsible for the compilation of the UK inventories of greenhouse gas and ammonia emissions from agricultural sources. Increasingly involved in research linking gaseous emissions research with quantification of other pollutant emission pathways and production measurements to enable identification of 'win-win' scenarios. Project leader on a number of multi-partner projects. Collaborate extensively both within UK and with research partners in Europe and elsewhere; regularly participate in UNECE and IPCC Task Force meetings regarding inventory methodologies and emission abatement strategies.

Previous research activities include more broadly based research on manure N utilisation within grassland systems and quantification and abatement of odours.
