Born in 1977 and of Swiss origin, Professor Samuel Jaccard is a specialist in Earth sciences. He trained in geology before exploring paleoclimatology, paleoceanography and chemical oceanography. His research aims to better document nutrient cycling and oxygen availability in marine ecosystems and the impact these processes bear on the cycling of carbon in the ocean interior. To do so, he mainly uses sedimentological and geochemical approaches and develops innovative tools to reconstruct climate-driven changes in the marine environment.

Samuel Jaccard obtained a Bachelor's and Master's degree in geology from UNIL, and then completed a thesis in Earth Sciences at ETH Zurich in 2006. His SNSF Early Postdoc Mobility Fellowship then took him to the University of British Columbia in Vancouver (Canada). Samuel Jaccard moved back to ETH Zurich where he worked as an senior researcher in climate geology for 5 years. He was then awarded an SNF professorship to establish an independent research group at the University of Bern and recently moved to UNIL as an associate professor. 

Samuel Jaccard has been involved in drafting the sixth assessment report of the IPCC (AR6) and is member of the Swiss Committee on Polar and High latitude Research as well as member of the executive board of CLIMACT, the joint UNIL-EPFL centre of Climate Impact and Action.
