Short Bio:

Dr. Demirel completed Optometry School at The University of Melbourne, Department of Optometry, in December 1989. He then commenced graduate work at the same institution and completed his PhD degree in May of 1995. Upon completion of his PhD, he completed a 2-year Post-Doctoral Fellowship at the University of California, Davis, working under Dr. Chris Johnson. After completing this Fellowship, he was appointed as an Assistant Professor of Optometry at Indiana University, where he taught Ocular Physiology, Retinal Physiology and Ocular Disease courses and taught within the School’s Masters and PhD programs in Vision Science.

At the start of 2002 Shaban moved to Portland to take an Assistant Scientist position at the Devers Eye Institute. He was promoted to the rank of Associate Scientist within the Devers Eye Institute in 2012.

In 2016, Dr. Demirel was appointed as the first Clinical Outcomes Research Scientist within Legacy Health. In this role, he supports all aspects of outcomes research, including study design / ideas development, human subjects review and regulatory compliance, data retrieval from large-scale data sources, such as electronic medical records, data analysis and statistics, data visualization and communication, and grant application / manuscript preparation. Dr. Demirel works across all aspects of the organization at Legacy Health, working with leaders, nurses, and physicians. He is currently involved in over 40 studies spanning medical specialties from podiatry to neurology, and everything in between.

Dr. Demirel was the Principal Investigator of the NIH funded “Portland Progression Project” and has been a Co-Investigator on numerous other federally funded grants. Dr. Demirel is a Fellow of both The American Academy of Optometry and The Association for Research in Vision and Ophthalmology, and is a Founding member of the Optometric Glaucoma Society. He has authored or co-authored over 70 papers and over 100 abstracts presented at scientific meetings in the US and internationally.

Research Focus:

As Legacy Health’s Director of Clinical Research, Dr. Demirel leads, promotes and guides clinical, population-based, and health economics outcomes research studies that seek to improve the end results of healthcare for Legacy patients, and for patients around the country and around the world. 

The main measure of success in this area of research is demonstration of benefits to our patients and society, but also arrival of these outcomes at a reasonable, sustainable cost. To meet these goals, we set up and conduct cross-sectional and longitudinal outcomes studies at Legacy Health to assess the impact of healthcare transformation on patient and population-based outcomes as well as health economics. Dr. Demirel provides expert consultation in the design and planning of studies and the use of outcomes research tools to perform evidence-based, comparative effectiveness assessment of changes in the provision of healthcare at Legacy Health.
