Fisher Professor of Natural History and Professor of Earth and Planetary Sciences
Andy Knoll is the Fisher Professor of Natural History at Harvard University. He received his B.A. in Geology from Lehigh University in 1973 and his Ph.D., also in Geology, from Harvard in 1977. Read more about Andrew H. Knoll
Zach studies two of the major transitions in the history of life as part of the Knoll Group: the origins of replicating molecules and the origins of the eukaryotic cell. For his PhD project, he discovered two new sources of microfossils in the 1.4 billion year old Belt Supergroup of Montana. The assemblages include unique specimens of Tappania plana, one of the earliest examples of complex eukaryotes and the first such fossils reported from Laurentia. Read more about Zachary Adam
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.
I received my PhD from the University of California, Santa Barbara; my MS from University of California, Los Angeles and my B.S. in Geology from Louisiana Tech University. I joined Andy Knoll's Lab in August of 2015 as a NASA Astrobiology Postdoctoral Fellow. Read more about Leigh Anne Riedman

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.
