Gerald H. Haug (born 14 April 1968 in Karlsruhe, Germany) is a German geologic climatologist, prize winner of the Gottfried Wilhelm Leibniz Prize and since 2007 he has a professorship at the ETH Zürich in Switzerland.^[1] In 2015 he became director of the Climate Geochemistry Department and Scientific Member at the Max Planck Institute for Chemistry in Mainz ^[2] and since March 2020, he became the new President of the National Academy of Sciences Leopoldina.^[3][4]

Haug graduated in Geology at the Karlsruhe Institute of Technology (KIT) in 1992 and received his PhD at the University of Kiel, Germany, in 1995.

From 1995 to 1996 Haug worked as a postdoc at GEOMAR, Helmholtz Center for Ocean Research Kiel, Germany. From 1996 to 1997 he had been a postdoctoral fellow in the Department of Oceanography at the University of British Columbia, Vancouver, Canada. Subsequently, he worked as a postdoctoral student at the Woods Hole Oceanographic Institution in Massachusetts,^[5] United States, and became later a research assistant professor at the University of Southern California, Los Angeles, United States (1997–1998). From 2000 to 2002, he worked as a senior assistant at the ETH Zürich, Switzerland, and habilitated in the Earth Sciences (2002).

Haug is signee of a protest note which points out the dangers arising from ignoring climate change.^[6][7]

Haug initiated the construction of the research sail yacht S/Y Eugen Seibold and coordinates the research.^[8]
