Research Interest

Dr. Christina Dyar’s research broadly focuses on understanding and reducing health disparities affecting LGBTQ+ populations. Her research focuses on groups of LGBTQ+ individuals that have been underrepresented in research, including bi+ individuals (i.e., individuals with attractions to more than one gender), LGBTQ+ women, non-binary individuals (i.e., individuals who identify outside of the gender binary), and BIPOC LGBTQ+ people. She is particularly interested in understanding mechanisms through which stigma-related stress (e.g., discrimination, microaggressions) impacts mental health and substance use. Her research often incorporates an intersectional perspective, aiming to understand the bias experienced by individuals with multiple marginalized identities (e.g., LGBTQ+ women, BIPOC LGBTQ+ individuals) and how this bias impacts their health. The overarching goal of her research is to inform interventions aiming to reduce health disparities impacting LGBTQ+ populations.
