Critical Studies on Men and Masculinities (CSMM) has been a rapidly growing area of research within Gender Studies and Feminist Studies over recent decades. This GEXcel research field builds on the work in the earlier GEXcel Research Themes: Research Theme 2 (Deconstructing the hegemony of men and masculinities: Contradictions of absence) and Research Theme 9 (Gendered sexualed transnationalisations, deconstructing the dominant: Transforming men, “centres”, knowledge/practice). It also represents a longstanding development of national, Nordic, European and international research in the three universities and associated universities of key researchers, along with their large research networks and collaborations. It draws on the work of past and present international research projects (e.g. CROME, The Study of the Role of Men in Gender Equality), editing of key journals (e.g. Men and Masculinities; NORMA: International Journal for Masculinity Studies), book series (e.g. Routledge, Sage), and extensive international publishing. By highlighting the naming and deconstruction of men and masculinities, this field also contributes to gender studies on knowledge production and other GEXcel research fields. The research field aims to develop the work further through explorations of theorising men and masculinities, transnational change around men and masculinities, masculinity and technology, and other questions.
