MS/PhD Position in Aquatic Biogeochemistry and Microbial Ecology at SUNY ESF State University of New York College of Environmental Science and Forestry in United States

Solange Duhamel’s lab at the University of Arizona is recruiting a Postdoctoral Research Associate in marine microbial ecology for the NSF Biological Oceanography–funded P-MixSwitch collaboration with Susquehanna University. The project studies prasinophyte mixoplankton —single-celled marine algae that can both photosynthesize and consume bacterial prey—to understand whether they switch from photosynthesis to feeding when phosphorus becomes scarce, and how that behavior affects carbon cycling in...

Oak Ridge National Laboratory (ORNL) is recruiting a Postdoctoral Research Associate in Plant-Soil Interactions and Coastal Biogeochemistry within the Environmental Sciences Division. The project is part of the interdisciplinary Exploring Gulf Region Ecosystem Transitions (EGRET) collaboration, which studies disturbance-driven ecosystem transitions across the U.S. Gulf Coast using field observations, laboratory mesocosms, AI/ML, remote sensing, process-based modeling, and advanced analytical tec...

PhD Assistantship at Louisiana State University in the Wetland and Aquatic Biogeochemistry Lab for research on phosphorus dynamics and harmful algal blooms (HABs) in coastal river and estuary systems in southeastern Louisiana. The project examines how land-use change , internal sediment loading , and seasonal hydrology influence phosphorus availability and water-quality impairment in the Lake Pontchartrain Estuary and its tributaries. The student will lead field-based research including river tr...

Jean Lim, Assistant Professor at Florida International University, is recruiting a PhD student for Fall 2027 in microbial ecology and related biology research. The project areas include chemosymbiosis in lucinid clams, the effects of microbes on seagrass growth, and the microbial diversity of Biscayne Bay water and/or sediment samples. The work combines field work, molecular biology and microbiology lab work, and 'omics data analysis . The position is described as fully funded through a teaching...

Postdoctoral Research Associate opportunity at the University of New Hampshire in Durham, New Hampshire, United States , working in the Ocean Process Analysis Laboratory on marine microbial ecology and oceanography. The project is supervised by Kai Ziervogel and is part of an NSF-funded study on nutrient-mediated interactions between plastic-derived DOC and the biological carbon pump . Research activities include bioassays with natural microbial communities from the Gulf of Maine, experiments wi...
