Justin Wright, PI

While much of my research has focused on wetland plant communities, I am willing to study any organism and work in any ecosystem to answer questions that interest me. I've worked in systems ranging from tropical streams to desert shrublands and am always looking for ways to explore the causes and consequences of patterns of biological diversity across the planet. My research program combines observational and experimental approaches with modeling to develop and test hypotheses and build towards synthetic ecological theory.

Jeri L. Parrent, Lab Manager & Research Associate

Jeri (she/her) joined the lab in September 2022. But she is no stranger to Duke. Jeri received her PhD at Duke University in the Graduate Program in Ecology, where she studied the influence of elevated CO2 and nitrogen deposition on plant-mycorrhizal community dynamics. In addition to looking after the lab, she is also investigating how increasing salinity along the North Carolina coast affects foliar fungal endophyte community structure and function.

David De La Mater, PhD Candidate

David (he/him) joined the lab in August 2018. He studies how environmental conditions influence the form of individuals and their role in the systems they inhabit, often using biogeographic theory as a lens through which to study this problem. David's PhD research uses salt marsh communities as a system in which to investigate this topic. He hopes to use the insights gleaned from his research to help inform conservation efforts. David is co-advised by Brian Silliman.

Aeran Coughlin, PhD Candidate

Aeran (they/them) is interested in the ecosystem and community-level effects of interactions between plants and soil microbes, and how these processes are impacted by climate change. In their PhD, Aeran seeks to understand the role of plant-microbe interactions in community composition shifts and large-scale tree mortality events (ghost forests) in forested coastal wetlands caused by sea level rise and salt water intrusion. They also seek to understand how fire interacts with these mechanisms in both the formation of ghost forests and post-mortality regeneration.

Richard Wong, PhD Candidate

Richard (he/him) joined the lab in August 2020. He is interested in climate change effects on food web structure and nutrient cycling within the fluid of pitcher plants. He hopes to use this unique system to inform conservation and preservation efforts regarding the response of larger aquatic systems to environmental change. He is co-advised by Jean Philippe Gibert.

Yuyang Wang, PhD Candidate

Yuyang Wang (she/her) joined the Bernhardt and Wright labs in Fall 2024. Yuyang is broadly interested in the ecological causes and consequences of plant species invasions within a global change framework. Her research explores how climate change influences the introduction and establishment of invasive plant species into novel environments, and the resulting ecological and impacts on plant community dynamics and biogeochemistry. To explore these questions, Yuyang’s work focuses on the Asian reed Phragmites and North American cordgrass Spartina in North American and Asian salt marsh ecosystems.
