Steven T. Brantley, Ph.D.

Scientist

Steven received his B.S. and M.S. in Biology and his Ph.D. (2009) in Integrative Life Sciences, all from Virginia Commonwealth University. His research at VCU focused on the consequences of shrub expansion on the Virginia barrier islands and was supported by the Virginia Coast Reserve LTER program. He subsequently worked as a post-doc at the U.S. Forest Service Coweeta Hydrologic Lab where he studied the effects of forest species composition on forest water use, the hydrologic effects of the hemlock woolly adelgid infestation, and strategies to conserve surviving hemlock trees. Steven has been at Ichauway since 2014 where he has engaged in diverse interdisciplinary work related to interactions between land and water.

O. Stribling Stuber, M.S.

Senior Research Associate

Stribling received her B.A. in Biology from Agnes Scott College and her M.S. in Ecology from the Odum School of Ecology at the University of Georgia. Her graduate research was based at the Jones Center, where she studied the impact of land use on the plant communities of geographically isolated wetlands and modeled change in wetland connectivity through time. Before pivoting to ecohydrology, her work in ecology focused on her first love: botany and vegetation surveys. In addition to southwestern Georgia, she has worked throughout Missouri, on the Georgia coast, and in South Africa, and studied semi-desert, prairie, savanna, forest, and wetland communities. Now, as the Research Associate for the Ecohydrology Lab, Stribling manages day-to-day lab operations, nerds-out on tidy data wrangling, and contributes to presentations and publications.

Suranjana Chatterjee, M.S.

Ph.D. Student

Suranjana received her B.Sc. in Electrical and Electronics Engineering from Bangladesh University of Engineering & Technology (BUET) and received her M.Sc. in Environmental Engineering from Lamar University, TX. Suranjana is now pursuing a PhD in Civil and Environmental Engineering at Auburn University. She is currently using hydrologic modeling and analysis to determine the long-term trajectory of nutrient deposition and biogeochemical function in geographically isolated wetlands (GIWs), which are widespread in many agricultural regions. Her research is part of a larger collaborative effort that will help to mitigate the effects of non-point source pollution from agriculture on water quality.

Justine Rojas Valadez, M.S.

Ph.D. Student

Advised by Daniel Johnson, University of Georgia. Justine received her B.S. in Biology at the University of California, Riverside in 2016 where she worked as an undergraduate researcher studying photosynthetic pathways of orchid species. She then went on to receive her M.S. in Biology at California State Polytechnic University, Pomona in 2018 where she studied biomechanics and anatomy of pygmy coast live oak in central California. Justine is now a PhD candidate in the Tree Physiology lab at the University of Georgia where she is focused on the effects of drought resistant traits on tree form and function. Specifically, she is looking at the ecological importance and functionality of water storage and capacitance (stored water in woody tissue released and used to support transpiration) among tree species.

Carlie Blackburn, B.S.

Senior Seasonal Technician

Carlie received her B.S. in Coastal Ecology and Environmental Sciences from The College of Coastal Georgia. While getting her degree, Carlie researched the effects of surrounding vegetation on water quality of residential ponds. After graduating, Carlie studied the restoration of maritime grasslands, including the reestablishment of culturally important sweetgrass populations, along the coast of Jekyll Island, GA. During her time on the coast, she also participated in eastern diamondback rattlesnake tracking, phytoplankton monitoring, and alligator population surveys. Her many interests include plant ecology and physiology as well as hydrology and water quality, and she is looking to pursue a career in those areas. Carlie is very excited to conduct research within the longleaf pine ecosystem and gain experience in the ecohydrology lab. In her spare time, Carlie enjoys exploring the outdoors, reading, and watching Star Wars.

Tess Eichner, B.S.

Seasonal Technician

Tess earned her BS in Water Resources with a minor in Geology from the State University of New York at Brockport. While there, she served as a research assistant in the environmental science department. The work focused on analyzing a swamp ecosystem, assessing the wetland’s filtering capabilities, and working with groundwater and stream data to establish a water balance. Additionally, for her senior seminar she investigated seasonal variations and the correlation between groundwater levels and precipitation in the swamp.

Will Guyette, B.S.

Seasonal Technician

Will earned his BS in Environmental Science with a minor in Wetlands Assessment and Planning from Westfield State University in Westfield, Massachusetts. While there, his coursework focused on wetland science and functions along with natural resource management. For his senior seminar he investigated the potential relationship between stream health and culverts through the utilization of aquatic macroinvertebrate sampling. In his free time, Will enjoys hiking, taking nature photos, and woodworking.
