Seema L. Clifasefi (she/her), PhD, MSW

Personal Statement

My research lies at the intersection of substance use, mental health, criminal justice and housing policy, with an emphasis on populations with lived experience of homelessness, substance use and/or involvement in the criminal justice system. Since 2006, I have been part of a collaborative academic and community-based research team evaluating the effects of Housing First, which entails the provision of immediate, permanent, low-barrier, nonabstinence-based housing to individuals with the lived experience of homelessness and alcohol problems. I am committed to and passionate about social and racial justice and my career path reflects this commitment. My most recent work focuses on the development, evaluation, and dissemination of a comprehensive, multi-dimensional program that aims to improve alcohol, health, and quality of life related outcomes for this population. Ultimately, through my work, I hope to help create positive social change by promoting understanding and compassion across different demographic and socio-economic class systems.
