Quentin has a broad scientific background related to climate changes issues, especially climate impacts, interactions between land use and climate and climate services. He is leading in our science team on land use and climate services, coordinates the European JPI-AXIS project LAMACLIMA, and is leading the work package on climate services products in the H2020 project PROVIDE.
His work is diverse and consists in coordinating research but also stakeholder engagement activities in a close cooperation with other team members and partner institutions. More specifically, he is in charge of the co-production of climate impact information and of online tools to make it accessible, in collaboration with scientists and stakeholders. In addition, he supports the science team on diverse issues related to climate physics and climate impacts for example during climate negotiations, and through media outreach activities targeted at a wider public.
Before joining Climate Analytics, Quentin was conducting academic research, focusing on the consequences of past and future land-cover changes on regional climate, and the evaluation of related processes in climate models. He conducted his PhD in Climate Science at ETH Zürich, where he later worked as a postdoc and where he is still affiliated. He has also authored a number of peer-reviewed articles.
