Broadly, Dr. Danielson's research interests and clinical work focus on treatment and prevention with high-risk adolescent and traditionally underserved populations, including basic and translational science studies that inform applied clinical research. Her particular areas of research and clinical expertise are in: 1) evaluating and disseminating integrated treatments for comorbid PTSD and substance use problems, as well as HIV sexual risk behaviors, among trauma-exposed adolescents, and 2) understanding the pathways from trauma and stress exposure to mental health problems. Dr. Danielson has been continuously extramurally funded (e.g., NIDA, NIMH, NIAAA, Brain & Behavior Foundation, SAMHSA) as an MUSC faculty member. Her studies include randomized controlled trials (RCTs), assessment and lab-based studies that focus on biomarkers and mechanisms underlying the etiology of PTSD, addiction, and other psychopathology among trauma-exposed young people (e.g., recent NIMH R01 examining threat-related negative valence systems, child victimization, and anxiety), and mixed methods investigations related to m-Health intervention development and evaluation.
