Dr. Northrup is an Associate Professor and Coordinator of Behavioral Science Training within the Department of Family and Community Medicine, as well as the Associate Director of the Behavioral Health and Addiction Research Program. He also has an appointment in the Center for Neurobehavioral Research on Addictions.

Dr. Northrup is a clinical psychologist, licensed in the state of Texas. His research specialties are focused on behavioral treatments for substance use disorders (SUD), secondhand and thirdhand smoke exposure (SHSe/THSe) prevention (particularly as SHSe and THSe relate to mothers and infants in the neonatal intensive care unit [NICU]), and smoking cessation.  Other populations of interest include pregnant women, mothers/families with a child in the NICU, and individuals who use opioids and illicit substances.

He was the PI for an NIH (NICHD)-funded R03 (data collection finished in 2018) focused on THSe in the NICU.  He served as a co-investigator and project director for one HRSA- and one NIH-funded project focused on reducing SHSe for infants discharged from a NICU to a household where individuals who smoke reside.  He was also the Site Principal Investigator for a completed NIDA Clinical Trials Network (CTN) study with individuals abusing or dependent on stimulants and a Protocol Manager for a recently completed NIDA CTN SUD pharmacotherapy study addressing methamphetamine dependence.  Currently he is a co-investigator on three studies, including: a pragmatic-effectiveness trial for opioid use disorders, a treatment development grant focused on combining motivational interviewing and acceptance/mindfulness-based interventions to help new mothers (who use substances) engage with SUD treatment and family planning, and innovative work on a medical-legal partnership addressing health-harming legal needs in primary care clinics.

He is a member of the Society for Research on Nicotine and Tobacco (and active member of the Finance Committee), American Psychological Association, Association for Behavioral and Cognitive Therapies, and the Society for Teachers of Family Medicine.

At UTHealth, Dr. Northrup served on the Faculty Senate from 2012-2018 (and rejoined in 2019), and currently serves on the HOOP and Research Committees.  He has mentored faculty members, neonatology and sports medicine fellows, postdoctoral fellows, residents, graduate students, and medical students. Dr. Northrup teaches behavioral science to 1st–3rd year Family Medicine Residents and has received the Dean’s Teaching Excellence Award for six consecutive years (2014-2019).

As an affiliate member of the Thirdhand Smoke Research Consortium, he participates in monthly Consortium webinars, collaborates with Consortium researchers, and shares his research through the Thirdhand Smoke Resource Center website at
