Professor Sirleaf’s scholarly agenda seeks to make visible the extant hierarchies in international law and to remedy the inequities reflected in it. Her work elucidates how seemingly neutral laws further global inequities. Her current research agenda sits at the crossroads between international human rights law and global public health law, where she analyzes the disproportionate distribution of highly infectious diseases and the role of international law in facilitating this result. Another branch of her scholarship sits at the intersection of international criminal law and transitional justice. This area of Professor Sirleaf’s scholarship proposes context-specific and locally informed approaches to providing redress to survivors of human rights violations and theorizes avenues for greater involvement of historically subordinated peoples in the making of international law. 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.
