Applications are reviewed on a rolling‑basis and applications may close before the deadline.

A research opportunity is currently available with the U.S. Geological Survey (USGS) located in Boulder, Colorado.

The USGS mission is to monitor, analyze, and predict current and evolving dynamics of complex human and natural Earth‑system interactions and to deliver actionable intelligence at scales and time frames relevant to decision makers. As the Nation's largest water, earth, and biological science and civilian mapping agency, USGS collects, monitors, analyzes, and provides science about natural resource conditions, issues, and problems.

The USGS programs supporting this research—the Water Mission Area National Water Quality Program and the Ecosystems Mission Area Toxic Substances Hydrology Program—focus on supporting national‑scale reconnaissance and prediction of per‑and polyfluoroalkyl substances (PFAS), harmful algal blooms (HABs), and associated toxins. Program goals emphasize targeted research and development to create advanced laboratory methods for detecting and documenting these emerging toxic threats. The programs also aim to advance understanding of the processes governing contaminant transport, persistence, natural attenuation, and geochemical transformation.

Together, these efforts strengthen the scientific basis for forecasting the development, duration, and decline of emerging contaminants across environmental matrices to improve prediction and management.

Microorganisms play an important role in the fate and transport of environmental contaminants through processes such as degradation, sorption, motility, and life‑cycle dynamics. This fellowship will investigate how microbiological processes influence the environmental behavior of HABs and PFAS by identifying and quantifying the mechanisms through which harmful algal species govern sorption, release, and transformation of PFAS in aquatic systems. You will have the opportunity to develop laboratory methods to characterize biological drivers that shape contaminant movement, retention, bioavailability, and exposure within phytoplanktonic and benthic algal communities.

This training provides exposure to interdisciplinary scientific approaches required to provide Federal, Tribal, and State partners with the data and tools needed for evidence‑based decision making and natural‑resource management.

• Collaborate with a supportive scientific community of interdisciplinary researchers across the USGS Ecosystem and Water Mission Areas.
• Design and implement laboratory experiments and apply advanced molecular biology and bioinformatics approaches to evaluate how environmental stressors influence contaminant fate with mentor guidance.
• Gain hands‑on experience integrating molecular technologies with microbial ecology and environmental chemistry.
• Receive training on methods used to produce holistic ecological assessments such as field observation, laboratory experimentation, and computational analysis.
• Strengthen scientific communication skills through the dissemination of research findings related to contaminant transport, ecosystem health, and decision‑support frameworks for resource managers.

The mentor for this opportunity is Jennifer Underwood (jcunder). If you have questions about the nature of the research please contact the mentor(s).

March 1, 2027. Start date is flexible and will depend on a variety of factors.

The appointment will initially be for one year, but…
