Provides students with the opportunity to review the epidemiologic basis for associating selected occupational and environmental exposures with health outcomes and to explore how this science might be used to develop and implement regulation of these exposures. Class sessions are divided between a critical evaluation of the science and a thoughtful engagement with how the science can inform policy.  Several sessions include guest experts who have worked at the interface of science and policy. Course Activities: Discussions based on selected epidemiologic studies and potential policy to address each problem. Course Note: Any EH course required as a pre-requisite or concurrent requisite. THIS CLASS HAS PRIORITY ENROLLMENT. Any student who does not meet the Wave 1 or Wave 2 criteria can add themselves to the waitlist (if enrollment requirements are met) at any time during the enrollment period. At the beginning of each priority wave, students on the waitlist who meet the Wave’s criteria will be automatically enrolled into any remaining seats in the course (pending no time conflicts). **Cross-Registrants and Non-Degree Students will be enrolled on a space available basis after the enrollment deadline for the course
