Purpose

The purpose of this video lecture is to discuss sibling comparisons and other family based research designs as tools for causal inference from observational data.

Meet the Guest Speaker

Patrick Quinn, Ph.D.

Assistant Professor, Indiana University Bloomington

Dr. Quinn studies the causes and consequences of substance use. His interests range across substances (e.g., from cigarette smoking to opioids) and across the lifespan (e.g., from prenatal drug exposure to medication treatment for ADHD in adults). Much of his current research examines pain and its treatment with opioid medications, using longitudinal health data on individuals and families and methods from epidemiology and behavioral genetics. As a licensed psychologist, Dr. Quinn is also broadly interested in other topics in mental health.
