Drawing upon training in sociology and implementation science, Dr. Knudsen’s research focuses on the diffusion of evidence-based practices in substance use disorder (SUD) treatment settings. She is currently leading a research project funded by the National Institute on Drug Abuse (NIDA) on the availability and quality of buprenorphine treatment for opioid use disorder. Dr. Knudsen’s prior studies, through support from NIDA and the Robert Wood Johnson Foundation, have addressed the implementation of smoking cessation services in addiction treatment organizations, the adoption of pharmacotherapies to treat alcohol and opioid use disorders, and the quality of SUD treatment for adolescents. In addition to her research, she is Editor-in-Chief of the Journal of Substance Abuse Treatment.
