Keynote Speakers and Panelists


Mark Rains, Ph.D.

Chief Science Officer for the State of Florida

Plenary Talk (Tuesday 6/6)

Mark Rains is an ecohydrologist with a B.A. in Ecology, Behavior, and Evolution, an M.S. in Forestry, and a Ph.D. in Hydrologic Sciences. His research is focused on hydrological connectivity from ridges to reefs, especially between hillslopes, wetlands, and headwater streams; the roles that hydrological processes play in governing ecosystem structure and function; and the roles that science plays in informing water-related law, policy, and decision-making. He has extensive experience in consensus building at the intersection of science and policy in wetland regulatory programs, including past and ongoing work providing the scientific justification underlying the federal definition of “waters of the US” subject to regulation under the Clean Water Act. He routinely contributes to this scientific debate in the legal arena, including two cases heard by the U.S. Supreme Court. He was appointed as the State of Florida's Chief Science Officer in 2021.
