Dr. Cohen is a Professor in the School of Forest, Fisheries, and Geomatics Sciences. He is an ecohydrologist with nearly 20 years of experience addressing water resource and ecosystem science challenges in Florida and around the world. Dr. Cohen received his PhD from the University of Florida in 2003 and joined the faculty in 2006. He has led research focused on hydrological restoration of the Everglades and Big Cypress, the changing ecological state of Florida’s springs, the deep links between forests and water, and the changing patterns of Arctic and Antarctic stream functions. This work has been funded by the National Science Foundation, the Department of Energy, all five Water Management Districts and the Department of Environmental Protections, and the US Army Corps of Engineers, and has resulted in over 120 publications.

Sarah graduated from the University of Florida with a Bachelor of Science in Environmental Science. She previously worked with UF/IFAS Extension to create educational materials focusing on Florida Friendly Landscaping, private wells and septic systems, and agricultural best management practices. As the Communications and Event Specialist for the Water Institute, Sarah develops and implements communication strategies to support the Water Institute, and she provides administrative assistance for the Water Institute’s programs.
Dr. Wendy D. Graham is a Professor in the Department of Agricultural and Biological Engineering and the founding Director of the Water Institute. She conducts research in the areas of coupled hydrologic-water quality-ecosystem modeling; water resources evaluation and remediation; evaluation of impacts of agricultural production on surface and groundwater quality; and development of hydrologic indicators of ecosystem status.
Currently, Dr. Graham serves as the Division Director for the Division of Research, Innovation, Synergies, and Education (RISE) within the Directorate for Geosciences (GEO) at the National Science Foundation. She earned her Bachelor’s Degree in Environmental Engineering from the University of Florida and holds a PhD in Civil Engineering from the Massachusetts Institute of Technology.

Rob earned his Doctor of Science degree at the Centre of Hydrogeology, University of Neuchatel (Switzerland) in 2007. His research activities were developing a finite element code for coupled, variably saturated flows, solving problems related to non-linearity, numerical instability and flow coupling, validation and verification.
His research at the Water Institute includes the development of a particle-tracking scheme tailored for coupled surface-subsurface flows as well as a finite difference scheme for coupling conduit flow, subsurface matrix flow and surface flow in karst systems. The objective of these schemes is to gain further insights into complex natural flow systems.
At this moment his research is focused on developing and testing methods to generate random 2-D and 3-D conduit networks for incorporation into watershed scale flow and transport models, and develop and test coupled discrete-continuum flow and transport models for the Silver Springs basin in Florida.
Nathan holds a B.S. and M.S. degree in Bioengineering from the University of Toledo. He earned his Ph.D. and M.E. in Environmental Engineering Sciences from the University of Florida in 2018. His dissertation, “Linking Landscape Hydrologic Processes to Spring Ecosystem Dynamics”, investigated potential drivers of change in the primary producer communities of Florida’s spring-fed rivers using a multi-scale modeling approach.
Some of his broad research interests include: the intersection of water, energy, food, and the environment; complex system dynamics; ecosystem dynamics and restoration; and the nature of how scientific inferences are obtained from data. He has experience in theoretical, applied, and experimental science in several disciplines, ranging from the development and implementation of mathematical models to the design and execution of field and laboratory experiments.
Nathan applies his multi-disciplinary experience to his research at the Water Institute, which focuses on understanding hydrological, ecological, and social dynamics in karst watersheds.
Ashlie earned her Bachelor of Arts in Human Resource Management from St. Leo University, Masters of Arts in Mass Communication from the University of Florida, and is working towards obtaining her PhD from Liberty University. Currently, Ashlie works with UF | Research Personnel Services, and serves as the Fiscal and Human Resources Liaison for the Water Institute. As the liaison, Ashlie supports the Water Institute staff with a variety of administrative and fiscal tasks.
Max Williams is the Director of Research Administration. He earned his BA from the University of Virginia and his Masters of Agribusiness from the University of Florida. Max has been with UF since 2003 and is a Certified Research Administrator.
