Roger Everett Summons

Roger Everett Summons (born 11 June 1946) is the Schlumberger Professor of Geobiology, Emeritus, at the Massachusetts Institute of Technology and Professor of Geobiology in the Department of Earth, Atmospheric and Planetary Sciences.

Summons' research spans biogeochemistry, geobiology, and astrobiology. His work employs organic geochemical methods to examine the lipid chemistry of modern and ancient microbes, the isotopic signatures of climate change, and the evolution and origins of life.

Summons was elected a member of the National Academy of Sciences in 2020. Provided by Wikipedia
