Professor Matiangai Sirleaf is an interdisciplinary international scholar, justice seeker, and human rights advocate who has worked over the last 16 years to unearth unjust hierarchies embedded in international law and to remedy the inequities that emerge and persist.
She is the Nathan Patz Professor of Law at the University of Maryland Francis King Carey School of Law. She holds a secondary appointment as a professor in the Department of Epidemiology and Public Health at the University of Maryland School of Medicine.
Professor Sirleaf has published widely and extensively. Her areas of expertise include public international law, international human rights law, global public health law, international criminal law, post-conflict and transitional justice, and criminal law. Her current research projects are focused on race and the histories of international human rights and health inequality and the law.
Professor Sirleaf is the editor of the first thematic print volume on Race & National Security (2023) with Oxford University Press. Her work has been featured in leading law reviews such as the Cardozo Law Review, the Columbia Law Review, the Texas Law Review, and the UCLA Law Review. Professor Sirleaf’s writing appears in several textbooks with Oxford University Press like Foundations of Global Health & Human Rights (2020) and Global Health Law & Policy: Ensuring Justice for a Healthier World (2023).
Her commentary and reflections also appear in several fora such as, AfronomicsLaw, American Journal of International Law, American Journal of International Law Unbound, American Society of International Law Insights, Bill of Health, Journal of Law, Medicine & Ethics, Jurist, Just Security, Opinio Juris, and Third World Approaches to International Law Review.
Professor Sirleaf’s research can be broadly categorized as critical international legal scholarship. Specifically, much of her writing falls in line with the Third World Approaches to International Law (TWAIL) tradition. TWAIL scholarship reconsiders the history and development of international law and highlights its colonial legacy. She has engaged in several projects where she looks at the embedded and hidden histories of international law in national security, in human rights, and in global health. Her work elucidates how seemingly neutral laws further global inequities. The common thread through all her scholarship whether examining issues of racial justice, civil and political violations, or socio-economic violations, is responsibility. International law conceives of responsibility in narrow ways and her scholarships seeks to render it more emancipatory.
Professor Sirleaf serves in several leadership positions. She is an executive editor at Just Security and is a member of the board of editors of the American Journal of International Law.
Professor Sirleaf has received several prestigious grants, awards, fellowships, and other honors. These include recognition as a fellow of the American Bar Foundation (2023), the University of Pittsburgh’s Teaming Grant (2020), the University of Pittsburgh Chancellor’s Distinguished Research Award (2019), the American Society of Law, Medicine & Ethics Health Law Scholar Selection (2019), the University Center for International Studies Faculty Fellowship (2018-2019), the Ford Institute for Human Security Research Grant (2016-2018), the New York University Martin Luther King, Jr. Humanitarian Award (2014), and a Fulbright Fellowship (2004).
Professor Sirleaf previously served as an associate professor of law at the University of Pittsburgh School of Law, as an assistant professor of law at the University of Baltimore School of Law, as well as a Sharswood Fellow at the University of Pennsylvania Law School.
