Research Interests

Dr. Gryczynski’s research interests include the intersection of medical care and behavioral health, particularly with respect to identifying novel approaches to service delivery that improve access, engagement, outcomes.  His health services research in addictions spans the spectrum of substance use problems, from early intervention studies with adolescents, to treatment research with populations characterized by high problem severity and complex comorbidities. Much of his work has emphasized practical strategies for service improvement in vulnerable and underserved populations. His research has included randomized trials of service strategies in addiction treatment, studies to inform intervention design, and investigations of individual and contextual factors that shape health behavior, service delivery practices, and patient outcomes. Adjunctive to these research activities, Dr. Gryczynski maintains an active interest in methodology and quantitative analysis.
