This course addresses the growing use of empirical methods in health law and policy, as well as in a variety of related fields, such as environmental policy, toxic torts, and biopreparedness. It provides basic training in the methods of epidemiology, risk assessment, and biostatistics. The goal of the class is to produce lawyers, policy-makers, and advocates who can critically evaluate study design and analytical methods and who have sufficient scientific literacy to be able to participate effectively in multi-disciplinary teams with scientists and health professionals. In addition to the core methodological components, focus topics—such as tobacco control, documenting human rights violations, and the impact of urban design on obesity—will be examined. There is no math or science prerequisite; quantitative skills needed for the class will be developed through instruction and exercises.
