Dr. Lindsay Squeglia is a Professor and licensed clinical psychologist at the Medical University of South Carolina (MUSC) in the Department of Psychiatry and Behavioral Sciences. She is the co-Director of the MUSC Youth Collaborative, and her National Institutes of Health-supported research focuses on: (1) understanding the effects of alcohol and cannabis use on brain development and (2) using neuroscience to improve prevention and treatment of adolescent substance use disorders. She co-leads MUSC's site for the nationwide Adolescent Brain Cognitive Development Study (ABCD) and has served in various roles on the ABCD Steering Committee, Novel Technology Workgroup, and Community Engagement and Dissemination Workgroup. She has a strong interest in community outreach and education efforts and leads the MUSC High School Teen Science Ambassador Program, providing high school students from groups underrepresented in the biomedical sciences with a three-phase internship experience in academic clinical research. She is the current Chair of the Research Society on Alcohol’s National Advocacy and Public Education Committee.


Dr. Squeglia is originally from South Carolina and grew up in the Charleston area. She received a Bachelor’s degree in Experimental Psychology at the University of South Carolina and a PhD in Clinical Psychology from the San Diego State University/University of California San Diego (UCSD). She completed her clinical internship in neuropsychology at the University of California Los Angeles and her postdoctoral fellowship in neuroimaging at UCSD. In 2023, she completed her Fulbright Senior Scholar fellowship at the University of Sydney, establishing a cross-national collaboration between the United States and Australia to improve health outcomes globally for youth struggling with substance use and mental health issues.


Dr. Squeglia is open to working with trainees at all career levels with an interest in understanding and addressing youth substance use. Potential trainees with prior substance use research experience who have an interest in working with data from ongoing or completed MUSC Youth Collaborative clinical trials studies and/or ABCD data are particularly encouraged to apply.
