The place of performance for this position is Annapolis, MD. This is an offsite position, however collaboration with CBPO staff will require quarterly site visits to the EPA’s Chesapeake Bay Program Office in Annapolis.

The Watershed Models will lead efforts to incorporate the best available scientific knowledge on nutrient and sediment sources, transport, and fate into the Chesapeake Bay Program (CBP) partnership’s Watershed Models. This position applies statistical and process-based modeling, research, and large-scale data analysis to improve the technical foundation, performance, and interpretation of CBP modeling tools and work directly with CBP technical and management work groups to develop modeling products that support science-based decision making.

• Candidates should have a PhD and professional experience in environmental science or environmental engineering.

• The successful candidate must demonstrate expertise in process-based and statistical models of watershed nutrient and sediment loading; experience applying Bayesian methods in prediction, estimation, and scenario applications; and familiarity with machine learning methods.

• Required skills include the ability to manipulate, analyze, interpret, and display data for use by broad audiences; programming ability across multiple platforms and languages including R Statistical Computing Language; and excellent written and verbal communication skills with demonstrated effectiveness communicating to Chesapeake Bay Program audiences.

• Conduct statistical and process-based modeling to quantify nutrient and sediment loading, transport, and attenuation across the Chesapeake Bay watershed.

• Lead efforts to integrate state‑of‑the‑science understanding of nutrient and sediment sources and transport into the CBP Watershed Model.

• Design, develop, and evaluate enhancements to model structure, inputs, and assumptions.

• Integrate multiple agricultural data sources for crop yields and acreage, fertilizer application, and livestock/poultry populations to improve estimates of agricultural nutrients and sediment inputs.

• Perform calibration, validation, and uncertainty analysis of the CBP Watershed Model via a Bayesian framework (CalCAST).

• Evaluate watershed model performance relative to monitored observations of streamflow, nutrient, and sediment loads across spatial and temporal scales.

• Apply statistical performance metrics to assess model fidelity and diagnose systematic errors.

• Apply advanced analytical methods including Bayesian approaches and machine learning to evaluate drivers of water quality change and advance modeling approaches.

• Conduct nutrient mass balance analyses to support model interpretation and management actions.

• Work directly with CBP technical and management work groups to identify modeling needs, develop technical products, and refine model applications.

• Collaborate with scientists, engineers, managers, and policymakers across the CBP partnership.

• Produce technical documentation, reports, and presentations communicating methods, assumptions, and results to CBP audiences.
