Dustin A. Lewis is a Senior Researcher at the Harvard Law School Program on International Law and Armed Conflict (HLS PILAC). With a focus on public international law sources and methodologies, Mr. Lewis leads research initiatives on normative and practical aspects of rules and standards related to wide-ranging contemporary challenges concerning armed conflict. He examines such topics as algorithmic “decision-making” in relation to war; impartial medical care and medical ethics; extraterritorial use of lethal force; legal end-points of armed conflict; and tensions at the intersections of counterterrorism frameworks and principled humanitarian action.
Mr. Lewis oversees HLS PILAC’s publications, research assistants, and online platforms. He contributes to the Program’s events, case studies, and workshops. And he regularly presents research to an array of audiences, such as governments (including military, foreign-policy, human-rights, and humanitarian departments); the United Nations system; members of the media; and non-governmental organizations. Before helping to found HLS PILAC in 2014, Mr. Lewis served in a variety of roles, including as a Senior Researcher at the HLS–Brookings Project on Law and Security; a Project Manager and Technical Lead at the Berkman Klein Center for Internet & Society and the HLS Library; a Program Associate at the Program on Humanitarian Policy and Conflict Research; and a Visiting Professional in Chambers at the International Criminal Court. He is an honors graduate of Harvard College (A.B.) and Utrecht University School of Law (LL.M.).
