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

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


My research focuses on the secondary use of electronic health record (EHR) data to research in both operational and clinical domains.  Some examples of research projects have included using audit log data for studying and improving clinical workflows, studying EHR documentation, using clinical data for predictive modeling, and studying the quality of EHR data.  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 with building parallel software tools for high performance computers at NASA and continued later with developing clinical informatics applications at Oregon Health & Science University. Throughout my professional career I have taught at the undergraduate and graduate levels, focusing on improving students’ problem solving, research, and project management skills.
