Dr. Aas is a Senior Research Scholar at the Kennedy Institute of Ethics and an Assistant Professor in the Philosophy Department at Georgetown. His primary areas of research are bioethics, metaethics, and social and political philosophy, with a significant focus on issues of disability: disability as social construct, disability and political egalitarianism, disability and health. These interests tie to broader projects: on the construction of social facts; the grounds of egalitarian justice; and the import of diverse embodiment for health care ethics and health policy. Dr. Aas earned a PhD in philosophy from Brown University in 2013, and served as a Fellow at the Justitia Amplificata Project at Goethe University in Frankfurt and a Fellow at the Department of Clinical Bioethics in the Clinical Center of the National Institutes of Health in Bethesda prior to joining the Kennedy Institute of Ethics.
