He currently leads a course in quality improvement and data analytics in the Masters of Management in Clinical Informatics program at the Duke University School of Medicine.

From the research perspective, Dr. Scales has a longstanding interest in the epidemiology of and patient care for urinary stone disease. Recent studies have redefined the epidemiology of urinary stone disease in the United States, compared the effectiveness of dominant stone removal technologies, and identified new opportunities for improving patient-centered and policy-relevant outcomes, such as unplanned care after procedural interventions. His research and perspective on urinary stone disease has been highlighted in U.S. News & World Report, Reuters, NPR, and the Wall Street Journal, among other media outlets.

Currently, Dr. Scales leads a diverse health services and clinical research program at the Duke Clinical Research Institute, where he is the Principal Investigator for the Scientific Data and Research Center for the NIDDK Urinary Stone Disease Research Network (U01).
