The successful candidate will have a working knowledge of statistical approaches for evaluation of environmental data (including Bayesian methods), chemical fate and transport mechanisms, mathematical exposure modeling, and environmental sampling. Mastery of data presentation and visualization as well as computer programming in R language is preferred.  Working knowledge of physiologically based pharmacokinetic (PBPK) modeling is also considered a plus.

This position offers a dynamic and challenging work environment, opportunities for professional development and leadership, and competitive compensation and benefits.
