Research Interests: Identity, particularly sexual and gender identities; their etiology, development, and consequences for mental and physical health and other adaptational outcomes; as well as the precipitating, moderating, and mediating factors essential for understanding the relations between identity and outcomes.

Dr. Rosario’s research focuses on the concepts of identity and stress, as well as the health and other adaptational implications of these concepts. The research has primarily centered on lesbian, gay, and bisexual individuals undergoing sexual identity development. The relations between stress and sexual identity development on the one hand to both health and adaptation on the other hand are of critical interest, as are the mediators and moderators of those relations. In addition, Professor Rosario is interested in the determinants of sexual orientation, the intersection of multiple identities, the unfolding of identity over time, and the role of psychosocial experiences in that unfolding.
She has published over 100 articles. She has an h-index of 47, according to Scopus.
Research and Scholarship Group
Dr. Rosario directs the Health and Identity Lab (HAIL).
HAIL focuses on biopsychosocial and disparities research that seeks to understand the strengths and vulnerabilities that directly or indirectly inform the individual’s mental and physical health as well as other, important adaptational outcomes. The work is guided by sensitivity to developmental process, individual by environmental transactions, and intersectionality of multiple identities (e.g., sexual, gender, ethnicity, race). A current project involves understanding the relations among child and adult attachment and the role of each in mental and physical health among a national sample of sexual minority and heterosexual adults.
