Laboratory of Niranjan S. Karnik, MD, PhD

The Karnik Lab is focused on community-based interventions for high-risk populations with psychiatric and substance use disorders. In the past, he has worked with refugee children on the Pakistan-Afghan border, street children in India, foster youth in Central Illinois, and incarcerated youth in California. He worked at a youth homeless shelter in San Francisco and is continuing this work with homeless youth in Chicago. Another major focus of his research is on using mobile health technologies to bridge the needs of vulnerable populations and enable providers to deliver services to underserved populations.

Dr. Karnik is based in the Department of Psychiatry & Behavioral Sciences in the Section of Population Behavioral Health and maintains appointments in the Section of Child Psychiatry and at the College of Nursing at Rush University. He served as medical director of The Road Home Program: The National Center of Excellence for Veterans and their Families at Rush. Finally, he is Co-Director of the KL2 Training Program and Director of the Center for Underserved Populations & Innovative Intervention at the Rush-University of Chicago Institute for Translational Medicine.

New Interventions for Substance Misuse

Substance use disorders are widely acknowledged as a major source of medical and psychiatric difficulties for patients and families. Dr. Karnik has been working with populations that disproportionately face challenges with substance use including alcohol, illicit drugs, cannabis and opiates. He and his team are working to develop scalable and population-based strategies for treatment of these disorders, and for expanding access the care. In addition, he has support for this research from the National Institute on Drug Abuse and also has had a training grant from the Substance Abuse Mental Health Services Administration.

The Stepping Stone Project

The primary purpose of this study is to examine the acceptability of delivering mental health interventions to abused homeless youth via smartphone technology. Additionally, we are investigating the extent to which these interventions improve trauma-related psychological symptoms and are aiming to establish smartphone usage patterns among homeless youth to inform future technology-based interventions. To accomplish this, we are providing homeless youth from the Night Ministry Shelter with a smartphone and offering them several therapeutic interventions over the phone: three brief cognitive behavioral therapy sessions with a therapist, the ability to text or call the therapist between sessions, two applications designed to improve relaxation and sleep hygiene, and daily health tips via push notifications.

Computation and Systems-Based Approaches to Substance Misuse

Dr. Karnik designed and launched the Substance Use Intervention Team (SUIT) at Rush. Research on this model is ongoing but the preliminary results show significant clinical impact and reduced length of stay from using this model. The program is also expanding via collaboration with the Afshar Lab at Loyola University to examine the ways that Natural Language Processing can be used to identify high-risk patients and to help guide targeted interventions.
