Jan Esper (born 1968) studied geography at the University of Bonn, where he later earned his doctorate. After a postdoc position at Columbia University in New York City, he continued his work on dendrochronology at the Swiss Federal Institute for Forest, Snow and Landscape Research (WSL), and qualified as a professor at the University of Bern. In 2018, Esper became a member of the Academy of Sciences and Literature. Since 2010, he has been a professor at the Department of Geography at Johannes Gutenberg University Mainz.[1]

Esper's research focuses on global climate change, paleoclimate, urban climate and dendrochronology. In 2020, he received the European Research Council (ERC) Advanced Grant to improve climate reconstructions from tree rings.[2] His research has notably included hockey stick graph temperature reconstructions.[3][4][5]
