Marc is a Senior Scientist and Deputy Science Area Leader in the Environmental Emissions Metrology group. He provides scientific direction in the measurement of pollutant and greenhouse gas (GHG) emissions to air from sources ranging from point-source emissions from industrial processes, including waste incineration and fibreglass manufacture, to diffuse sources, such as fugitive emissions from oil refineries and methane and ammonia emissions from intensive farming. He also leads work to measure the radiative balance of the atmosphere through ground-based solar observations.
Much of this work contributes to efforts within the International Organization for Standardization (ISO) and the European Committee for Standardization (CEN) to develop documentary standards that support environmental legislation. Marc serves as Convenor or UK expert on a broad range of Working Groups. These standards are relied upon to enforce legislation and support international commitments to monitor and reduce pollutant and GHG emissions.
Marc is a Fellow of the Royal Society of Chemistry (FRSC) and holds Chartered Chemist (CChem) status. Before joining the National Physical Laboratory (NPL) in 2002, he completed a Fellowship jointly sponsored by Johnson Matthey plc and MEL Chemicals at Queen's University Belfast, where he worked on novel catalyst discovery. Marc holds a PhD in Catalytic Chemistry from the University of Reading and Queen's University Belfast, and a BSc (Hons) from the University of Bath.
