Olivier leads the Climate, Chemistry and Ecosystems team. His research is about biogeochemical feedbacks in the climate system and their relevance to climate mitigation policies.
Areas of expertise:
Earth system modelling;
climate change, metrics and mitigation policies;
regional to global air pollution;
integrated assessment modelling.
Olivier is a science strategic head in the Met Office Hadley Centre. He leads and coordinates the work of the team on Earth System modelling and contributes to defining the strategy within Climate Research. His research interests include climate change, regional to global air pollution, aerosol-radiation-cloud interactions, data assimilation of satellite observations in atmospheric models for monitoring the atmospheric composition of the atmosphere, atmosphere-biosphere couplings and biogeochemical feedbacks in the Earth System, impact of irrigation on climate, impact of aviation on climate, climate mitigation policies, climate metrics, and integrated assessment modelling.
Olivier joined the Met Office in 2005. Prior to joining the Met Office, Olivier was leading the aerosol team in the Laboratoire d'Optique Atmosphérique where he became a CNRS Directeur de Recherche. He completed his PhD on aerosol-cloud-radiation interactions at the University Pierre and Marie Curie in Paris in 1995.
Olivier is an Editor of the Geophysical Model Development journal.
Olivier received the Prud'homme prize of the Société Météorologique de France for his PhD in 1996.
Olivier received the CNRS Bronze medal in 2000 for his research work.
Olivier received the EGU Outstanding Young Scientist Awards in 2004.
Olivier contributed to the 2007 Nobel peace prize through his participation to IPCC work.
Olivier is currently coordinator of the AEROSOL sub-project of the GEMS (2005-2009) and MACC (2009-) projects, chair of the UK land surface community model, JULES, management committee (2007-), co-leader of the COMBINE FP7 project on Earth System modelling (2009-), member of the Sand and Dust Storm-Warning Advisory and Assessment System (SDS-WAS) Regional Steering Group for Northern Africa/ Middle East/Europe Node (2008-), member of the scientific steering committee of the LEFE-EVE programme of CNRS-INSU (2006-).
Olivier has been a lead author of the "Special Report on Aviation and the Global Atmosphere" (1999) of the Intergovernmental Panel on Climate Change, a lead author of the "Third Assessment Report" (Climate Change 2001: The Scientific Basis) of the Intergovernmental Panel on Climate Change, and a contributing author to the 2002 WMO report on ozone.
Olivier has been the coordinator of and/or participant to several national, European, and international projects (e.g., PHOENICS, DAEDALUS, PROMOTE, CAPACITY, EUCAARI, COMBINE, GEMS, MACC).
Olivier is a former Associate Editor of the "La Météorologie" journal of the "Société Météorologique de France and a former Thematic Editor of the "Annales Geophysicae" journal of the European Geosciences Union.
Altogether Olivier has authored and co-authored more than 80 peer-reviewed papers.
