Lyons has a long history with the Astrobiology Program and has served as PI on numerous projects supported through elements of the Program. Lyons’’ leadership and innovation had led to important developments in paleoenvironmental proxies used to track redox changes in the rock record of Earth. His research has helped advance the understanding of how the diversity of life on Earth today is tied to gradual changes in biogeochemical cycles and biosphere evolution over billions of years.
