Prior to his National Park Service position, Nick was the Research Director at the South Florida Water Management District, directing a team of 120-plus scientists conducting research in support of ecosystem restoration. Nick received his B.S. and M.S. in biology at the University of West Florida, and his Ph.D. in microbial ecology at Oregon State University. He was a faculty member in the Biology Department at the University of Mississippi, and was a tenured Associate Professor of Biology when he returned to Florida. Nick presently is an affiliate faculty member at Florida Atlantic University (Department of Geosciences), and at the University of Florida (Soil and Water Science Department). He also served five years on the national Board of Directors of the Sierra Club, a 120-yr-old environmental organization with more than 750,000 members, and served two terms as its Vice-President and one as Treasurer.

Dr. K. Ramesh Reddy is the Director of the UF/IFAS School of Natural Resources and Environment and a Graduate Research Professor of the UF/IFAS Soil, Water, and Ecosystem Sciences Department. He holds a Ph.D. in soil science with specialization in biogeochemistry from Louisiana State University. He conducts research on coupled biogeochemical cycling of nutrients and other contaminants in wetlands and aquatic systems, as related to water quality, coupled biogeochemical cycling, ecosystem productivity, and restoration. He has worked on Florida’s wetlands and aquatic systems for more than 45 years. Dr. Reddy established an interdisciplinary program on biogeochemistry of wetlands and aquatic systems, through the Wetland Biogeochemistry Laboratory (WBL) established within the SWSD. Since its establishment in 1987, the WBL has provided a home for graduate students from various disciplines, postdoctoral associates and visiting scientists.

Dr. J. Scott Angle is the University of Florida’s Senior Vice President for Agriculture and Natural Resources and leader of UF/IFAS. As chief executive of the agriculture and environmental sciences arm of a leading land-grant university, he champions public science as a path to improve lives and reduce human suffering. Dr. Angle leads nearly 2,300 employees who work in all 67 Florida counties. UF/IFAS encompasses the College of Agricultural and Life Sciences, the Florida Cooperative Extension Service, and the Florida Agricultural Experiment Station.

Dr. Angle previously served as the Director of the National Institute of Food and Agriculture (NIFA) from October 2018 to July 2020. Prior to that, Angle worked for 24 years as a Professor of Soil Science and Associate Director of the Maryland Agricultural Experiment Station and Maryland Cooperative Extension at the University of Maryland. His early work focused on the study of losses of nutrients from agro-ecosystems and their impact on the Chesapeake Bay. He also studied the impact of heavy metals on the food chain with the goal of protecting our food supply from these harmful elements. Later, he concentrated his research on phytoremediation, the use of plants for extraction of heavy metals from soil. In 2005, he moved to Athens, Georgia, where he served as Dean and Director of the College of Agricultural and Environmental Sciences at the University of Georgia for 10 years.

A frequently published author, Angle is a fellow in the American Society of Agronomy and the Soil Science Society of America. He is also a Fulbright Fellow, having worked at Rothamsted Research in the UK.

Angle served as President and CEO of the International Fertilizer Development Center (IFDC) from 2015 to 2018, where he oversaw a staff of more than 800 and coordinated development projects in diverse regions of the world. IFDC provides solutions to alleviate global hunger and poverty through the promotion of economic development and self-sufficiency.

Angle earned his B.S. and M.S. at the University of Maryland in Agronomy and Soil Science, respectively. He earned his Ph.D. from the University of Missouri with an emphasis on Soil Microbiology.

Dr. David Krabbenhoft is a Senior Research Scientist (emeritus) with the U.S. Geological Survey (USGS) Mercury Research Lab, located in Madison, Wisconsin. Dave began working on environmental mercury sources and cycling in 1987, and since that time the topic has consumed his professional life. In 1993, Dave established the USGS’s Mercury Research Laboratory (MRL), which includes a team of multi-disciplinary mercury scientists and a state-of-the-art analytical facility strictly dedicated to low-level speciation and isotope analysis of mercury in all environmental media. Since its inception, the MRL as conducted mercury research projects that span environments as far ranging as the each of the world’s oceans, and freshwater systems from Alaska to Florida, California to New England, and more recently across the entire Great Lakes ecosystem.

While environmental mercury research has been his focus, the specifics of his research are wide ranging, including: atmospheric mercury sources and transport at local-to-global scales; cycling and fluxes of mercury in aquatic and terrestrial ecosystems; biogeochemical controls on the bioavailability of mercury to methylation; and, human epidemiology studies. Over his career, Dave served on a large number of national and international level committees and panels regarding mercury pollution of the environment and has given testimony to the US Congress on several occasions. In 2006, he served as the co-host for the International Conference on Mercury as a Global Pollutant, which was attended by over 1,200 researchers representing 54 countries across the globe. Since 1990, he has authored or coauthored over 190 papers on mercury in the environment. In 2015, Dave was promoted by USGS, Department of the Interior to Senior Research Scientist (ST), the highest level attainable by a scientist in the federal government system.

Lynn Wingard has been a Research Geologist with the U.S. Geological Survey since 1991 and is Project Chief of two Everglades projects. The majority of her work over the last 25 years has been in support of Everglades Restoration. Her research focuses on analyzing estuarine sediment cores to determine changes in coastal environments over the last 100-5000 years. Lynn’s combination of paleontological and modern data has provided Everglades resource managers with information on changes to freshwater flow into the estuaries, changes in habitats and species in the coastal environments, and long-term trends in sea level and climate. Her examination of centennial to millennial scale changes provides a long-term perspective on the impacts of drivers on the ecosystem. She has served on numerous scientific panels, is an associate editor of two journals, and is adjunct faculty at two universities. Lynn has served on several RECOVER Project Delivery Teams, most recently the Biscayne Bay Southeast Everglades Restoration PDT.
