About
Barbara Sherwood Lollar, CC has published on stable isotope geochemistry and hydrogeology, the fate of carbon-bearing fluids and gases such as CO2, CH4 and H2 in ancient fracture waters in the Earth’s crust, deep subsurface microbiology, and the remediation of surface drinking water supplies.
Barbara Sherwood Lollar is a University Professor in Earth Sciences at the University of Toronto, a Canada Research Chair in Isotopes of the Earth and Environment, and Dr. Norman Keevil Chair. She is also Past-President of the Geochemical Society
A recognized leader, Sherwood Lollar has served on many advisory boards including NSERC Council, the United States National Academy of Sciences Space Studies Board, the Honors and Recognition Committee for the American Geophysical Union, and Royal Society (London) Sectional Committee in Earth and Environmental Sciences. She was Chair of the 2018 United States National Academy of Sciences “Strategy for Astrobiology and the Search for Life in the Universe” and is a member of the NAS Space Studies Board (2016-2022).
