Dr. Northrup is an Associate Professor and Coordinator of Behavioral Science Training within the Department of Family & 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 (SHSe) and thirdhand smoke exposure (THSe) prevention (particularly as SHSe and THSe relate to mothers and infants in the neonatal intensive care unit [NICU]), and smoking cessation. Currently he is the PI for an NIH (NICHD)-funded R03 focused on THSe in the NICU.

He was the Site Principal Investigator for a completed NIDA Clinical Trials Network study with individuals abusing or dependent on stimulants. He is also a co-investigator/data manager/study coordinator for several other research projects, including studies involving SUD pharmacotherapy, motivational interviewing, and acceptance/mindfulness-based interventions. Populations of interest include pregnant women, mothers/families with a child in the NICU, and individuals who use opioids and illicit substances.

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

At UTHealth, Dr. Northrup has served on the Faculty Senate since 2012 and has mentored faculty members, postdoctoral fellows, residents, graduate students, and medical students. Dr. Northrup teaches behavioral science to 1st–3rd year Family Medicine Residents and mentors medical students pursuing research endeavors. He has received the Dean’s Teaching Excellence Award for four consecutive years (2014-2017).
