Dr Andrew Brown is a Principal Scientist in NPL’s Air Quality and Aerosol Metrology Group. Andrew leads NPL’s work on the physical and chemical characterisation of particles in air, which includes measurements of aerosol particle number concentration, particle charge concentration and particle size distribution. Current research interests include measuring the composition of non-exhaust vehicle emissions, source apportionment of pollutants in ambient air, and traceable measurements of particle surface area as a metric relevant to the negative health effects of airborne particles.
Prior to joining the Air Quality and Aerosol Metrology Group in December 2020, Andrew spent a year on secondment at the Environment Agency developing a capability to use air quality data from satellite-based instruments to investigate regulated emissions to air. Andrew’s previous roles at NPL include leading the energy gases research area and being Interim Lead of NPL’s Project Management Office.
Andrew has a PhD in physical polymer chemistry from the University of Durham, is a Fellow of the Royal Society of Chemistry and a Chartered Chemist, and holds the Project Management Qualification from the Association for Project Management.
