The EPA National Student Services Contract has an immediate opening for a full-time Ecological Modeling Support position with the Office of Research and Development at the EPA facility in Duluth, MN.  

The Office of Research and Development at the EPA supports high-quality research to improve the scientific basis for decisions on national environmental issues and help EPA achieve its environmental goals. Research is conducted in a broad range of environmental areas by scientists in EPA laboratories and at universities across the country.

What the EPA project is about

The Center for Computational Toxicology and Exposure (CCTE) supports ORD by providing solutions-driven research to rapidly evaluate the potential human health and environmental risks due to exposures to environmental stressors and ensure the integrity of the freshwater environment and its capacity to support human well-being.  CCTE researchers are developing and applying cutting edge innovations in methods to rapidly evaluate chemical toxicity, transport, and exposure to people and environments.  Within CCTE, the Scientific Computing & Data Curation Division (SCDCD) develops the knowledge and information architecture necessary for integrating, transforming, and managing large scale data streams related to assessing the risk of chemicals. SCDCD creates and manages online tools and ensures compatibility with existing chemistry, toxicology, and other experimental data sources.

What experience and skills will you gain?

As a team member, you will support research under the Chemical Safety for Sustainability (CSS) research program on modeling of human exposure to chemicals. The team member will assist with support of data needs, including acquisition and development of datasets to parametrize ecological models, assistance in the testing or evaluation of models, and basic summaries and analyses of data. The work of the team member may include gathering additional datasets from online sources, formatting datasets into standard templates, and uploading datasets into databases.
