Lucas Menzel studied geology at the University of Würzburg. He graduated with a degree in hydrology from the University of Freiburg, Freiburg im Breisgau, Germany, in 1989 and the Ph.D. degree from the Swiss Federal Institute of Technology (ETH), Zurich, Switzerland, in 1996, with his thesis on the simulation of evapotranspiration at the soil-vegetation-atmosphere interface. After working as a Postdoctoral Researcher with ETH, on the generation of evapotranspiration maps for the Hydrological Atlas of Switzerland, in 1998, he joined the Potsdam Institute for Climate Impact Research (PIK), Potsdam, Germany, where he conducted intensive investigation on the simulation of future flood events in the context of climate change. Since then, he has been involved in several projects dealing with the future development of water resources in arid and semiarid regions. After working at PIK for several years, from 2004 to 2009, he was with the University of Kassel, where he was an Assistant Professor with the Center for Environmental Systems Research (CESR), leading the further development of the global water model WaterGAP. Since 2009, he has been a Full Professor in Hydrology and Climatology with Heidelberg University, Heidelberg, Germany, and since 2020, he has been the Director of the Institute of Geography. In 2017, he was a Research Fellow with the University of Waterloo, Canada.
