The central aim of our lab is to answer a critical question: Why are LGBTQ+ people more likely to think about, attempt, and die by suicide, and what can we do to prevent it? To answer this, we conduct rigorous quantitative, qualitative, and mixed-methods research to study the biopsychosocial mechanisms underlying heightened suicide risk among LGBTQ+ people. Our projects take a cells-to-society approach, meaning that we are interested in studying risk and protective factors across levels – from individual psychological processes and neural responses to rejection, to interpersonal relationships and social networks, to societal norms and public policies. We are especially committed to integrating theory with innovative methodologies to advance the field of LGBTQ+ suicidology. Our research is grounded in psychology, epidemiology, community-based methods, and public health, with the ultimate goal of informing effective, equitable suicide prevention strategies.
