This volume honors the work of Dan Healey in Russian, East European, and Eurasian Studies (REES), reflecting the full range of his research interests, from Soviet and Russian history of sexuality to the studies of medicine and the Gulag. The volume includes contributions from Healey’s former students and colleagues, who together represent several generations, diverse genders and sexualities, multiple national traditions, and a variety of academic disciplines. Its fourteen essays pay special attention to his influence in crossing, breaching, and even breaking the disciplinary, geopolitical, and generational boundaries that have defined REES since the Cold War.Contributions to the volume demonstrate how Healey’s influence has not simply broadened the scope of REES overall, but just as importantly aided in current efforts to decolonize the field. As a result, the volume offers a provocative survey of contemporary research into the questions of power and sexuality, medical expertise, and archival methods. As such, it will appeal to both students and researchers interested in these topics.
