Piehler’s research focuses on microorganisms and microbially mediated processes in coastal land-water interfaces (particularly wetlands) and near-shore waters. He has conducted work on a broad range of microbial systems including microphytobenthic communities, epiphytic microalgae, benthic bacterial communities, bacterioplankton, and phytoplankton. The land-water interface is an area of intensive biogeochemical cycling and trophic interactions involving microorganisms. It is also an area of extensive human activity, making the interactions of pollutants and native microbial communities in the land-water interface a significant issue in developed coastal environments.

Piehler was the founding head of CSI’s Estuarine Ecology and Human Health Program in 2004. In this role, he works to bring together scientists from an array of disciplines to help find solutions to the complex issues facing coastal North Carolina by providing unbiased information to government, non-government and private organizations.

He is an Associate Professor at UNC Chapel Hill’s Institute of Marine Sciences in Morehead City and is the Director of Graduate Studies for the Curriculum for the Environment and Ecology at UNC Chapel Hill.
