Michelle R. Hribar, Ph.D., M.S.

  • Assistant Professor of Medical Informatics and Clinical Epidemiology, School of Medicine


I apply operations research, data analytics, and informatics methods to clinic processes for improving efficiency. This research combines my educational background in mathematics, operations research, and computer science, my IT experience working with clinicians, and my training as a National Library of Medicine (NLM) postdoctoral fellow.  After studying high performance computing and parallel algorithms in graduate school, my professional career started building parallel software tools for high performance computers at NASA and continued later with developing clinical informatics applications at Oregon Health & Science University. My current focus is on research—studying clinical workflows and applying computer science and operations research techniques for improving their efficiency. I use timing data from the electronic health record to evaluate use patterns of the EHR and for improving outpatient ophthalmology clinic workflows. Throughout my professional career I have taught at the undergraduate and graduate levels, focusing on improving students’ problem solving, research, and project management skills.
