I received the information below from my colleague Dan Levy at the FDA.
The FDA Center for Food Safety and Applied Nutrition has a training position for a post doctoral toxicologist responsible for exposure and safety/hazard/risk assessments of food borne contaminants. The incumbent often provides comments on and participates in formulating guidelines for science policy concerning food substances, particularly when it concerns methods of assessment for estimating exposure to food-born environmental contaminants. The incumbent also often provides comments in response to requests for advisory opinions sent to the Agency concerning such dietary exposure assessments. The best candidates will be able to demonstrate strong quantitative skills and a background or interest in dose response modeling. Training is under the auspices of the Oak Ridge Institute for Scientific Education (http://see.orau.org/ProgramDescription.aspx?Program=10105 ). Appointment is for 1 year with renewals for up to 5 years. This is a non-laboratory research position located in College Park, MD. Interested candidates should contact me at firstname.lastname@example.org
