Summary of Expertise

Professor Hammack is an expert on sexual and gender diversity, with particular interest in the following areas:

 

·       Newer or more visible sexual and gender identities in the 21st century, including nonbinary gender, pansexuality, ace spectrum identities, polyamory, sexual subcultures and identities

·       Experiences of stigma among those expressing intimate diversity, including those who practice consensual nonmonogamies, kink/BDSM, and those who form queer chosen families

·       Queer men’s health and identity development in the 21st century, with a focus on queer masculinities, sexual health and subcultures, and stigma and mental health

·       The use of psychedelic medicine among those diverse in gender or sexuality 

·       Paradigm, theory, and method in the social sciences, with a particular interest in narrative theory and methods, social justice, cultural psychology, and life course theory

 

Embedded in all of Professor Hammack’s current work is an interest in the following:

 

·       Generational and intersectional patterns of experience

·       Social technology mediation (i.e., the role of social media in experience and development)

·       Legal, institutional, and social policies regarding sexual and gender diversity

·       Accessibility and practical application of knowledge produced

 

Professor Hammack is currently accepting new graduate students to join the Sexual and Gender Diversity Laboratory whose interests align with any of the items outlined above. He also works closely with undergraduates interested in conducting independent senior theses on any of these topics.
