Summary of Expertise

Professor Hammack studies sexual and gender identity diversity in social, historical, and political context. His specific interests include how those who hold minoritized sexual or gender identities develop their identities, make meaning of social change, and navigate normativity; queer men’s health, identity development, and sexual cultures in the twenty-first century; sexual subcultures; queer forms of masculinity; intimate diversity, including same-gender relationships, polyamory, kink/fetish relationships, asexuality, and chosen families. His projects employ multiple methods, including narrative, ethnographic, and survey methods. Professor Hammack has also been a leader in the development of narrative theory and the promotion of narrative and other qualitative methods in psychology.
