Seth Wenger, Principal Investigator. Seth is an associate professor in the Odum School of Ecology and serves as the Director of Science for the UGA River Basin Center. He earned a PhD in Ecology from UGA in 2006 and spent a little over five years as a staff scientist with the nonprofit Trout Unlimited before returning to UGA in 2014 (yes, I know that doesn’t quite add up).

Anna Baynes, Master’s Student in Conservation Ecology and Sustainable Development. Anna received her B.S. in Environmental Sciences from Elon University. After graduating, Anna worked at UGA Marine Extension as a Marine Education Fellow where she did aquarium husbandry and taught a variety of classes, her favorite being estuary trawls. She also worked at the Oyster Hatchery and the Skidaway Institute of Oceanography studying marine microbes. Anna then worked at the UGA Savannah River Ecology Lab as a research technician studying the spread of rabies in wildlife. Anna is interested in studying freshwater ecology; specifically, fish ecology focusing on diversity, hydrologic alterations, and other anthropogenic impacts to improve conservation efforts.  

Phillip Bumpers, Lab Coordinator, PhD Student (co-advised by Amy Rosemond). Phillip is the joint research coordinator for the  Wenger lab in the River Basin Center and the Rosemond lab in the Odum School of  Ecology. Phillip received his MS in ecology at the Odum School in Dr. Rosemond’s lab where he studied how nutrient enrichment altered the growth and diet of larval salamanders. He leads a several projects that monitors fish populations in the Etowah and Conasauga rivers that aims to determine how populations of species of interests are changing over time. He has also been heavily involved in several other projects in the lab investigating flow ecology relationships of ecosystem processes and drivers and patterns of conductivity in urban streams. Phillip is broadly interested in how global change affects stream ecosystem structure and function with a particular interest in nutrient enrichment, climate change, and urbanization.

caitlin

Caitlin Conn, PhD Candidate (co-advised by Amy Rosemond). Caitlin received her B.A. from Hendrix College with majors in Biology and Religious Studies, and went on to hold a variety of conservation, environmental education, and academic research positions with state agencies, nonprofits, and universities. Caitlin is broadly interested in how human activities, especially management practices, impact freshwater ecosystems and how scientific research can be used to better inform these management practices. Her current research aims to quantify the effects of different flow conditions, and thus different management strategies, on the key ecological functions of stream metabolism and nutrient retention. Specifically, she is examining how changes in primary production, as a response to varying flow conditions, affects these ecological functions.

Kyle Connelly, Master’s Student (co-advised by Amy Rosemond). Originally from Northeast Ohio, Kyle earned his B.S. in Wildlife and Fisheries Resources from West Virginia University and has worked on a number of water quality monitoring projects for both watershed NGOs and a regional government agency.  After graduating, Kyle spent two years in the Philippines as a Coastal Resource Management Volunteer with the Peace Corps, where he facilitated the collection of local environmental data and helped write a five-year management plan for the area.  Kyle is most interested in examining how effective current watershed management strategies are in achieving their desired ecological outcomes and how resilient these systems are under changing socio-ecological conditions.

Mackenzi Hallmark, Research Technician. Mackenzi earned her B.S. from Virginia Tech in Biology. Her previous work as a technician includes amphibian conservation research at Virginia Tech, feral hog population monitoring at Tall Timbers Research Station, and longleaf pine ecosystem hydrology and wetland monitoring at the Jones Center at Ichauway. Mackenzi joined the Wenger Lab in July 2021.

Madeline Martinez, Research Technician. Madeline earned a BS in Marine and Atmospheric Science from the University of Miami in 2020. She joined the Wenger Lab in May 2021 in a technician position that is shared with the Capps Lab.

Laura Naslund, PhD Student (co-advised by Amy Rosemond). Laura received a B.S. in Biology from Duke University where she studied the transport of selenium from mountaintop mining-impacted streams to terrestrial predators through emerging aquatic insects. She is broadly interested in human impacts on chemical fate and transport in freshwater ecosystems. For her dissertation, Laura is studying the impact of small impoundments on greenhouse gas emissions and nitrogen fluxes in stream networks to inform evaluations of the costs and benefits associated with dam removals.

Shishir Rao, PhD Student. Shishir is an engineer-turned-ecologist interested in hydrology, freshwater ecology and watershed management of tropical river ecosystems. Broadly, his research focus is on understanding how altered hydrology affects ecology-flow relationships and how reservoirs can be better managed to restore hydrological connectivity and incorporate downstream socio-ecological demands. His past research in the Western Ghats of India dealt with a) understanding the socio-ecological and hydrological impacts of small hydro power projects and 2) quantifying the degree and extent of hydrological alteration by large dams with a focus on developing environmental flows. At the University of Georgia, Shishir is enrolled as a PhD student under the Integrative conservation and ecology program.

edstowe

Ed Stowe, PhD Student (co-advised by Mary Freeman). Ed received a B.S. at Yale University in Ecology and Evolutionary Biology and subsequently worked for various conservation, sustainability, and resource management entities. He is interested in quantitative research that is motivated by aquatic conservation questions. Current projects include assessing the pattern and scale of fish declines to understand the underlying causes of these declines, examining how the population response of fishes to stream discharge variability is mediated by traits and context, and determining whether stream restoration practices enhance the abundance and diversity of fishes.

sameera

Sameera Talati Gujarathi, PhD Student (co-advised by Susana Ferreira). I have worn several hats in my professional career so far. From being an engineer working in the power sector in India, to being a marketing executive and business development manager working in the remote farms of Southeast Asia, India and China to working as an business analyst in the mature biotech industry in Denmark and North America, my varied work experiences drew me back to academics. I am drawn to investigate the interplay between development and environmental degradation or conservation. With a background in Economics from UGA and now as a PhD student with ICON and the Odum school of Ecology, my research focuses on investigating the trade-offs between growth and conservation, socio-economic and ecological impacts of economic growth, and how development shapes conservation attitudes. As a mother of two children who will probably see a very altered world by the time they reach adulthood, sustainable growth is something I care about deeply and I hope my research will address those kind of issues.
