Project Title: The Latino School Readiness Gap: Engaging parents, educators and pediatricians in novel primary care solutions

Dr. Peterson is an Assistant Professor at OHSU in the Department of Pediatrics, Division of General Pediatrics. Her LHS K12 research project centers on the intersection of health and education to promote school readiness in Latino communities. Dr. Peterson’s long standing research interest in early education disparities comes from personal and professional experiences including work as a middle school teacher and as a primary care provider at a county health center serving primarily Latino children. Prior research done by Dr. Peterson utilizes her community based participatory research skills and has focused on the attitudes of parents and the barriers to school readiness (SR) in the Latino population and the role of the pediatric health system to address the SR needs of Latino children and families. Dr. Peterson’s career goal is to become an independently funded physician-scientist incorporating innovative, evidenced-based SR interventions into pediatric clinical practice, reducing SR and academic disparities among underserved children. Dr. Peterson completed her medical training at the University of California, San Diego, pediatric training at Stanford, and her Masters of Public Health at the University of California, Berkeley.

Assistant Professor

Home Institution: OHSU, Department of Medicine, Division of General Internal Medicine

Health System: OHSU

Project Title: Transporting treatment effects from clinical trials to people with concurrent methamphetamine and opioid use

Dr. Cook earned his Masters of Science in Public Health from the University of Miami Miller School of Medicine and his PhD in Epidemiology from the UCLA Fielding School of Public Health. He is an Assistant Professor at OHSU in the Department of Medicine, Section of Addiction Medicine. Dr. Cook’s research focuses on improving understanding and treatment of complex patients with multiple substance use disorders (SUDs). He is especially interested in epidemiologic and statistical methodology and applications to SUD treatment research. Dr. Cook’s K12 project aims to translate SUD treatment effects established by National Drug Abuse Treatment Clinical Trials Network (CTN) studies to “real world” populations concurrently using opioids and methamphetamine (MA). He will also look for differential CTN intervention impact by geographic regions, characteristics, and behaviors (e.g. MA injectors vs. non-injectors) of opioid and MA users.
