Dr. Chasson's research primarily focuses on obsessive-compulsive disorder, hoarding disorder, body-focused repetitive behaviors, and autism spectrum disorder. His work examines the intersection of these conditions with emotional regulation, cultural factors, and co-occurring disorders. He has conducted extensive research on OCD in diverse populations, including studies on African Americans, Chinese adolescents, and incarcerated individuals, highlighting the importance of cultural considerations in diagnosis and treatment. His recent work has increasingly focused on the relationship between OCD and autism spectrum disorder, as well as the role of family involvement in treatment outcomes.

Analysis of his most recent publications reveals a consistent focus on clinical assessment tools, treatment outcomes, and cross-cultural applications of OCD research. His work spans epidemiological studies, clinical trials, and meta-analyses, with particular attention to vulnerable populations including adolescents, African Americans, and individuals with co-occurring conditions. His research on hoarding disorder has been especially influential, contributing to standardized assessment approaches and understanding emotion dysregulation in this population.

Dr. Chasson has been actively involved in research examining Medicaid waiver services for autism spectrum disorder, investigating how family-directed care coordination impacts treatment outcomes. His work bridges clinical practice with health policy considerations, particularly regarding service delivery for neurodevelopmental disorders.

He maintains an active research laboratory focusing on obsessive-compulsive and related disorders, with particular emphasis on developing and validating assessment tools across different cultural contexts and investigating the mechanisms underlying treatment response in OCD and hoarding disorder.
