Orla Muldoon is an Irish social and political psychologist and professor of psychology at the Queens University Belfast and University of Limerick. Muldoon's research concerns how groups memberships and social identities mediate the relationship between health, well-being as well as social and political attitudes. She is the author with colleagues of the Social Identity Model of Traumatic Identity Change. She has examined the impact of the war in Northern Ireland on children, the impact of domestic violence, brain injury and sexual violence, and social identity and post-traumatic stress disorder. Muldoon has made major contributions to debates raising concern's about Ireland's response to the COVID-19 pandemic because of the lack of diversity on the panel making recommendations and has made major contributions to understanding of violence against women in Ireland for which she was awarded a European Research Council Research Impact and Engagement Prize in 2024.
