The Aquatic Ecology and Biogeochemistry lab began at UNC in Fall 2022, and as we continue to grow, we are eager to hear from you - stay tuned using our 'Join the Lab' page.
Nick Marzolf, Postdoctoral Scholar
Nick is a postdoctoral scholar in the Duke BGC lab. He began as a postdoc on our NSF Macrosystems project focused on predicting GHG flux from rivers across the US in January 2023, and just accepted a position at the Jones Center at Ichauway!
Nick earned his PhD in 2021 from NCSU working with Dr. Marcelo Ardón studying carbon fluxes, disturbances, and spatiotemporal variability in Neotropical headwater streams. His interests are in the movement of carbon in freshwater ecosystems, from greenhouse gas evasion to uptake and assimilation in food webs.
Nguyen Tien Anh Quach, Ph.D. Student
Anh is a Ph.D. student in the Department of Geography at UNC. He came to the US in 2016 and received his B.S. in Environmental Science in 2020 from Troy University, where he dove headfirst into the field of freshwater ecology and biology. As a Master’s student at Towson University, he is examining the long-term impacts of urban development and climate change on stream water chemistry, hydrology, and benthic macroinvertebrate communities (His favorite bug is the heptageniid mayfly!).
In the DelVecchia Lab, Anh is interested in studying the contribution of chemotrophy and methanotrophy to the aquatic food web and macroinvertebrates’ roles in greenhouse gas emission.
Tayton Alvis, UNC 2025
Tayton is pursuing a bachelor’s degree in Environmental Sciences with minors in Biology and GIS. He is currently assisting in stable isotope sample analysis and curation of aquatic macroinvertebrate collections. He is primarily interested in aquatic ecology and biodiversity, and hopes to pursue a graduate degree in the natural sciences.
Hannah Obenaus, UNC 2023
Hannah is pursuing a bachelor's degree in environmental science with a concentration in ecology and natural resources and a minor in GIS. She is working with Colorado bug and salt release projects. She is interested in using her GIS skills to study biotic and abiotic relationships in different ecosystems. She hopes to continue doing environmental science research and explore different topics.
Chloe Hall, UNC 2024
Chloe is pursing an Environmental Science B.S. with an Ecology and Natural Resource Management concentration and a GIS minor. She will be assisting Professor DelVecchia on her various aquatic macroinvertebrate projects and stable isotope analysis. She is passionate about freshwater ecology and hopes to continue to pursue a career in field ecology and hydrology.
Former Lab MEmbers
Emmy Stewart, UNC 2023
Emmy is pursuing a major in environmental studies with a concentration in ecology and a minor in Spanish. She is currently working on a project regarding salt release in streams and is looking into the feasibility of a UAV project mapping stream surface area. In the future, she is interested in researching agroecology, specifically the impact of agriculture on freshwater systems.
Lydia Stranathan, UNC 2026
Lydia is pursuing a bachelor’s degree in Environmental Studies. She is currently working on creating an educational webpage to communicate findings from Cement Creek, CO. She hopes to work in urban planning or conservation in the future with interests in topics such as homelessness, climate change, and creating green environments.
