Oliver's interests are in atmospheric composition, chemistry and transport, and in understanding how natural and anthropogenic emissions of trace gases affect regional air quality and global climate.
He has spent more than 20 years developing and applying numerical models of atmospheric processes over a range of scales from urban to global, and has published more that 70 refereed journal papers. His recent research in atmospheric sciences has focussed on:
Intercontinental transport of ozone and its precursors. This research informs air quality policy through the UN-ECE task force on Hemispheric Transport of Air Pollution (HTAP).
Indirect climate impacts of short-lived gases such as NOx and CO through their influence over tropospheric chemistry. This has involved contributing to the last three IPCC climate assessment reports.
Atmosphere-biosphere interactions and the role of atmospheric chemistry in the Earth System. Recent research has focussed on biogenic emissions of isoprene and the consequent effects of biofuel cultivation on human mortality and crop yields in Europe, and on ozone dry deposition processes under the NERC Atmospheric Chemistry in the Earth System (ACITES) network.
Anthropogenic and meteorological factors controlling surface ozone and air quality over East Asia. This builds on almost 10 years experience working in the US and Japan and ongoing collaboration with the Chinese Academy of Sciences in Beijing on air quality.
Characterising and reducing uncertainty in atmospheric chemistry-transport models. This research has contributed to a number of recent international model intercomparison projects, including ACCENT, HTAP and CCMI.
Oliver is a Fellow of the Royal Meteorological Society, and was a member of council 2010-2013. He is an editor of Atmospheric Science Letters, a journal of the Royal Meteorological Society, and Scientific Online Letters on the Atmosphere, a journal of the Meteorological Society of Japan. He currently serves as a NERC Peer Review College member.
