Michael Lehning (born 1967) is a German environmental and atmospheric scientist. He is a professor of atmospheric sciences at EPFL (École Polytechnique Fédérale de Lausanne), the head of EPFL's Laboratory of Cryospheric Sciences, and head of the group Snow Processes at the Swiss Federal Institute for Forest, Snow and Landscape Research (WSL).[1][2][3]

Career

Lehning received a Diploma in geo-ecology from the University of Bayreuth and a Master's degree in atmospheric sciences at University of California, Davis both in 1993.[4] He pursued post-gradual studies in statics and an PhD in atmospheric physics and graduated in 1996 from ETH Zürich with a thesis on "Transport processes and regional pollutant budgets over topography of varying complexity" supervised by Albert Waldvogel.[5]

In 1997, he became a scientific collaborator at the Institute for Snow and Avalanche Research (SLF) of the Swiss Federal Institute for Forest,WSL located in Davos, Switzerland. In 2001 he became head of the research and development team on Process Models, and from 2006 to 2018 he was head of the research unit on Snow and Permafrost.[3][6]

Since 2011 he has been a full professor at the EPFL and and the head of the Laboratory of Cryospheric Sciences at EPFL's School of Architecture, Civil and Environmental Engineering.[1][2] Since 2018 he also been head of the group Snow Processes at SLF.[3]

Research

Lehning's research is focused on the investigation of the dynamics of snow masses and the prevention of risk setting in mountainous regions.[7] He developed modeling software for the elucidation of dangerous situations. He also explored the interactions between the cryosphere (ice-covered surface of the planet) and climatic change|climatic changes.[8]

His scientific work targets the interaction of the cryophere with the atmosphere, in particular snow processes;[9][10] warning and forecasting of natural hazards;[11] Turbulence and boundary layer flows;[12] and mountain hydrology and permafrost modeling.[13][14]

Distinctions

In 2009, he received a call to a full professor position in in environmental physics at the University of Tübingen, an offer that he refused. In 2001, he received the Award for extraordinary performance in transfer of scientific knowledge to users from the Swiss Federal Institute for Forest, Snow and Landscape Research.[3]
