Dennis Krämer is a sociologist at the University of Münster.

His research focuses on the social conditions of gender-diverse people, especially in sport and healthcare, with particular attention to how knowledge about sex and gender diversity is discursively produced. One strand of his work examines how the participation of gender-diverse people in sport and the eligibility regulations of sports governing bodies have changed over time. He studies how inclusion and exclusion intersect with broader sociopolitical developments, ideas of fair competition, and changes in biomedical knowledge. A second strand explores the role of technology in crisis situations, particularly during public health emergencies. In that context, he founded the international network Resilient Healthcare in Times of Multiple Crises (RE-CARE).
