Jan Esper

Jan Esper (born 1968) ^[1] is the head of the dendro sciences division at the WSL (Wald Snee und Landschafft - en:Forest, Snow and Landscape) division of the Swiss Federal Institute of Technology (ETH). His research interests are Global Climate Change, Palaeoclimatology and Vegetation Dynamics.

His research has been part of the Hockey stick controversy with his temperature reconstructions, that have been cited as being evidence for both sides of the controversy.
