Dr. VanderLaan’s research examines gender expression across the lifespan and sexual orientation development. Much of this work focuses on questions surrounding same-sex sexual orientation, gender-nonconforming behaviour, and transgender identity to enhance our understanding of human diversity. Identifying factors associated with psychological well-being among individuals who are members of sexual orientation and gender minority groups is also a major focus, particularly as well-being relates to social experiences with family members and peers.

To provide a comprehensive understanding, Dr. VanderLaan’s research emphasizes biological, psychological, and socio-cultural processes and integrates developmental, cross-cultural, and evolutionary perspectives. In addition, his research program integrates a variety of methodological approaches, including lab-based experiments and behavioural observation, cross-cultural field research, clinical research, neuroimaging, survey and questionnaire studies, and archival studies.
