Details for: Ann Pearson


Ann Pearson is the Murray and Martha Ross Professor of Environmental Sciences at Harvard University. Her research focuses on applications of analytical chemistry and isotope geochemistry to Earth and environmental processes. Through studying the chemistry of natural organic molecules, her work yields insight about conditions on Earth today, in the past, and about potential human impacts on our future. Recent projects have focused on understanding pathways of lipid biosynthesis relevant to the global carbon and nitrogen cycles and paleoclimate, and on new technologies for biomolecular stable isotope analysis. Pearson received a Fellowship for Science and Engineering from the David and Lucille Packard Foundation in 2004, a Radcliffe Institute Fellowship in 2009, and was named a Marine Microbiology Initiative Investigator of the Gordon and Betty Moore Foundation in 2012.
