Portrait of Andrew H. Knoll

Andrew H. Knoll

Andrew Knoll is the Fisher Professor of Natural History in the Department of Organismic and Evolutionary Biology at Harvard University. He is broadly interested in the evolution of life, the evolution of Earth surface environments, and the relationships between the two. His work focuses in part on the first four billion years of Earth's history – Archean and Proterozoic paleontology and biogeochemistry, including the early diversification of prokaryotic metabolisms, the initial radiation of eukaryotic life, and the rise of large complex algae and animals. He is also actively involved in Mars exploration, both as part of NASA's 2004 MER missions and in the planning for future landings.
