Clinical Research Description
Dr. Osborn is an Assistant Professor of Medicine and Biomedical Informatics and an investigator in the Center for Diabetes Translational Research, Center for Health Services Research, and Center for Effective Health Communication. She graduated summa cum laude from California State University, San Marcos with a BA in psychology and sociology. She earned an MA and PhD in social/health psychology and graduate certificate in quantitative research methods from the University of Connecticut. Finally, she earned an MPH and completed a post-doctoral fellowship in health services research at Northwestern University, Feinberg School of Medicine.

Dr. Osborn's research focuses on theory-based, technology-assisted behavioral intervention design and evaluation for adults with diabetes, including how to leverage patient portals and mobile devices to promote patient self-care (e.g., medication adherence). Her research investigates disparities in technology use and adherence to self-care, how to leverage technology to reach diverse patients, and whether and when technology works to exacerbate or reduce health disparities. Methodologically, she uses qualitative methods to inform intervention design, and a cadre of quantitative techniques to validate instruments, test mechanisms, and evaluate intervention efficacy.
