Dr. Locke’s research and practice focus on how decision makers use environmental health science and toxicology in regulation and policy-making and how environmental health sciences influence the policy-making process. His areas of study include radiation policy, as well as the law of humane science and policy, with an emphasis on how in-vitro and non-mammalian toxicology data can be incorporated into regulatory decision making under US laws. He also studies the impact of the US legal system on the development of non-mammalian toxicology and alternatives to animals in testing. Dr. Locke directs the School’s Doctor of Public Health program in Environmental Health Sciences and is a faculty member of the Center for Alternatives to Animal Testing and the Center for Law and the Public’s Health. He has published papers in peer reviewed journals and law reviews, including the Columbia Journal of Environmental Law, The Environmental Law Reporter, Health Physics, and the Journal of Toxicology and Environmental Health.
Dr. Locke has served on 6 National Academy of Sciences study committees, including the committee that updated the Guide for the Care and Use of Laboratory Animals.
