Aquatic Sciences People - The Jones Center at Ichauway Research Labs

People

Nicholas S. Marzolf, Ph.D.

Assistant Scientist

Nick received a B.S. in Biology from the University of Florida (2013), a M.S. from the University of Georgia and the Jones Center at Ichauway (2015), and a Ph.D. from North Carolina State University (2021). His research began in documenting the invasion of Lake Seminole by the apple snail Pomacea maculate and transitioned to quantifying carbon fluxes in Neotropical streams. He was a Postdoctoral Associate at Duke University and expanded work on carbon fixation and greenhouse gas emissions from rivers across the US, integrating ecosystem models with high resolution data collection.

Caitlin Sweeney

Research Associate

Caitlin received her BS in Environmental Science from Auburn University. She then continued to receive her master’s degree at Auburn under Dr. Eve Brantley in the Department of Crop, Soil, and Environmental Sciences. Her research focused on soil amendments for bioretention cells, a form of green infrastructure for stormwater management. After graduating, Caitlin worked as a Watershed Program Assistant with Alabama Extension where she contributed to presentations and publications for the Alabama Private Well Program and Alabama Watershed Stewards Program. She joined the Jones Center Aquatic Biology Lab as a Research Associate in 2021. She is excited to have the opportunity to learn more about freshwater biology and contribute to research in the Flint River basin. Her favorite mussel is the Sculptured Pigtoe (Cyclonaias infucata).

Natalie Horn

Seasonal Technician

Natalie received her BS from Coastal Carolina University where she majored in Marine Science. Since being at the Jones Center, she has become a Flint River mussel hugger and freshwater enthusiast of the lower Flint River basin. She hopes to continue expanding her knowledge and attend graduate school in the future. Her favorite mussels include Elephant Ears (Elliptio crassidens), Southern Elktoes (Alasmidonta triangulata), and Florida Sandshells (Lampsilis floridensis).

Stephen W. Golladay, Ph.D.

Scientist

Dr. Golladay’s interests include the ecology of streams and wetlands, the impact of human land use on water quality and aquatic invertebrates, and the impact of variation in hydrology on ecological processes and aquatic communities Recently, he has developed an interest in the ecology and conservation of rare and endangered freshwater mussel species.

Dr. Golladay has served as a technical advisor to the Sand County Foundation, Georgia EPD, DNR and Water Management districts in Florida. He has developed training activities for resource professionals in partnership with the U.S. Fish and Wildlife Service. Dr. Golladay also has assisted in the development of programs to enhance the
natural resource awareness of regional educators in cooperation with regional Georgia Youth Science and Technology.
