IU's Responding to the Addictions Grand Challenge initiative involves a broad array of IU's world-class faculty. Through 30+ interdisciplinary projects, divided into five categories, our researchers are working to address the biological and psychological underpinnings of addiction; the family and social structures that contribute to addiction and facilitate or discourage recovery; and community-based strategies to improve resilience and policy and laws. Meet the researchers who are doing their part in the addictions crisis.
