Murray and Martha Ross Professor of Environmental Sciences; Harvard College Professor
Ann Pearson is the Murray and Martha Ross Professor of Environmental Sciences. Her research focuses on applications of analytical chemistry, isotope geochemistry, and molecular biology to biochemical oceanography and Earth history.
Professor of the Natural Sciences and co-Director of Graduate Studies
Isotope geochemistry and historical geobiology. Re-animating ancient ecosystems and ocean chemistry using stable isotope systems, chemical speciation techniques, modern microbial experiments (for calibration) and theoretical considerations.
Before joining the Knoll Group, Drew received a B.S. in Biological Sciences from Cornell University and a Ph.D. in Geosciences from Virginia Tech. As a paleontologist and geobiologist, his work focuses on fossils of complex eukaryotes in the late Neoproterozoic-early Paleozoic interval (~1000-450 Ma) of the geologic record. By studying the paleobiology and paleoenvironments of these fossils, his work aims to understand the rise of animal life and its impact on the Earth system.
Post-doctoral Fellow Junior Fellow of the Society of Fellows Knoll - Pierce - Lauder Groups
Elizabeth is both a paleontologist and biological oceanographer. She is broadly interested in the evolution, structure, and function of ocean ecosystems. She uses a multi-proxy approach to study how the open ocean ecosystem has changed through time, with a focus on how it has responded to climate and biotic events in the past. Elizabeth works primarily with ichthyoliths, microfossil fish teeth and shark scales found in deep-sea sediments world wide, which preserve an unparalleled record of fish diversity, abundance, and community structure through geologic time.
