Gerard Porter is a Non-Stipendiary Fellow with the Program on Science, Technology & Society at the Harvard Kennedy School of Government. He is also a Lecturer in Medical Law and Ethics at the University of Edinburgh. His current research focuses on the regulation of transnational clinical trials. Using the United States and India as case studies, he is mapping the ways in which law and policy are evolving in both countries and seeking to understand how science and ethics travel between these quite different economic and socio-cultural contexts.
