James Heiss, PhD

Assistant professor of Hydrogeology in the Department of Environmental, Earth, and Atmospheric Sciences at the University of Massachusetts – Lowell

Mr. Heiss’s research entails coastal groundwater-surface water interactions, climate change and sea level rise impacts to coastal groundwater resources, and chemical fluxes along the land-sea transition zone. His current research focuses on the hydrologic forcings (waves, tides, currents, extreme precipitation, and storm surge) that move water and chemicals between aquifers and nearshore surface water bodies. He explores these hydrologic processes using field experiments, numerical models, and quantitative synthesis of large datasets. Prior to joining UMass Lowell, Dr. Heiss was a postdoctoral fellow at the National Academy of Sciences in Washington, DC. He holds M.S. and Ph.D. degrees in Geology from the University of Delaware.

Christopher J. Russoniello, PhD

Hydrogeologist in the University of Rhode Island Department of Geosciences

Mr. Russoniello is a hydrogeologist in the University of Rhode Island Department of Geosciences. His work focuses on coastal groundwater, saltwater intrusion, surface water/groundwater interactions, cold-region hydrology, and the impacts of rising seas and changing climate on freshwater resources. Prior to joining URI, he earned M.S. and Ph.D. degrees in Geology from the University of Delaware, completed a postdoctoral fellowship at Syracuse University, and was assistant professor at West Virginia University. Mr. Russoniello has served on 15 graduate committees, mentored many undergraduate researchers and is current and former mentor to two NSF EAR postdoctoral fellows. Teaching interests focus on the coast, its complex processes, the interaction between the ocean and groundwater, and environmental data skills. Outside work Mr. Russoniello enjoys playing on water (liquid and frozen) and spending time with his wife, daughter, and dog.
