Dr. Locke is an environmental health scientist and attorney who holds an MPH from Yale University School of Medicine and a DrPH from the Johns Hopkins University Bloomberg School of Public Health. He is also a graduate of Vanderbilt University School of Law and is licensed to practice before the bars of the states of New York, the District of Columbia, the United States District Court for the Southern District of New York and the United States Supreme Court.

Dr. Locke’s research and practice target the intersection of environmental health sciences, policy and law in the areas of radiation policy and law and the use of new, non-animal based methods in toxicity testing and research. His areas of study include the laboratory animal law, the 3Rs, implementation of new scientific methods in toxicity testing, radon risk science and policy, radiation risk analysis, uranium mining, protecting space workers, high-level radioactive waste disposal and the application of low dose radiobiology to policy making. He is the author and co-author of several book chapters and numerous papers, and has published in policy and scientific journals as well as law reviews.
