Mark A. Lever

Dr. Mark Lever (born 1977) is a microbial ecologist who studies the role of microorganisms in the global carbon cycle. He is a professor of environmental microbiology in the Department of Environmental Systems Science in the Institute of Biogeochemical and Pollutant Dynamics at ETH Zurich.

Dr. Lever earned his MA in Marine Biology at the Boston University Marine Program at Woods Hole in 2002 and his PhD in Marine Sciences at the University of North Carolina, Chapel Hill in 2008. He worked as a postdoctoral scientist at Aarhus University from 2009 to 2014,[1] when he joined the faculty of ETH Zurich. Lever is a member of the Deep Life Scientific Steering Committee and Synthesis Group 2019 for the Deep Carbon Observatory[2] and is an associate editor for Frontiers in Microbiology.

In his research, Dr. Lever investigates factors that determine the presence, abundance, community composition, and metabolism of microorganisms in aquatic sediments and in Earth's crust.[3][4] In 2013 he discovered that microbes survive deep in the crust by living off of chemical energy in the “dark biosphere.” His work has a special focus on the burial, remineralization, and synthesis of organic matter in aquatic sediments and in Earth’s crust.[5][6]
