Interested in the global consequences of everyday actions, she is the author of Burned Bridge: How East and West Germans Made the Iron Curtain (Oxford Univ. Press, 2011). Her current book, Inventing Autism under Nazism: The Surveillance of Emotion and Child Euthanasia in the Third Reich, examines Hans Asperger’s creation of the autism diagnosis in Nazi Vienna, situating it within the context of efforts to define the national community and the murder of disabled children. Related research at the Spatial History Project, Forming Selves: The Creation of Child Psychiatry from Red Vienna to the Third Reich and Abroad, traces the transnational growth of the field of child development.
