Olayinka O Shiyanbola, PhD, B.Pharm

Associate Professor

Dr. Shiyanbola’s research examines patient perceptions in medication use and its impact on medication adherence, health literacy and the elimination of health disparities. Specifically, Dr. Shiyanbola studies the perceptions of illness and medicines among underserved populations. She explores how to utilize and interweave patient perspectives into the development of tailored patient-centered medication use interventions. In her other areas of interests, Dr. Shiyanbola empirically redesigns prescription and health information documents to improve patient understanding and medication safety. She utilizes socio-behavioral and health psychology theories in her studies and employs qualitative, quantitative, and mixed methods approaches in her work. Dr. Shiyanbola was a NIH Mixed Methods Research Training Program Scholar, a National Institute of Minority Health and Health Disparities Research Institute Scholar, and a NHLBI/OBSSR Behavioral Clinical Trial Fellow. She had a NIH/ICTR KL2 Career Development Award and is funded on several projects to develop and implement educational, psychosocial and behavioral interventions to improve medication use. Dr. Shiyanbola is currently an appointed member of the National Academies of Science, Engineering, and Medicine Roundtable on Health Literacy.

Dr. Shiyanbola is an Associate Professor in the Social and Administrative Sciences Division in the School of Pharmacy. She received her Pharmacy degree  (B.Pharm) from the University of Ibadan in Nigeria and her Ph.D. in Pharmaceutical Socioeconomics from the University of Iowa in Iowa City. For her PhD degree, Dr. Shiyanbola examined beliefs in medicines, changes in beliefs overtime and its impact on patient health outcomes. Before joining the University of Wisconsin School of Pharmacy faculty in 2013, Dr. Shiyanbola was a faculty at South Dakota State University College of Pharmacy. In the PharmD curriculum, Dr. Shiyanbola teaches on the Social and Behavioral Aspects of Pharmacy Practice, Psychosocial Aspects of Medication Use and the Role of the Pharmacist in the Public Health System. In the Health Services Research in Pharmacy Graduate Program, she teaches the design, approach, and use of Mixed Methods for PhD Pharmacy and Health Science Students.
