I am a Professor in the Department of Medical Informatics & Clinical Epidemiology (DMICE) in the School of Medicine at Oregon Health & Science University (OHSU). I served as the inaugural Chair of DMICE from its inception in 2003 through 2022. I am a leader and innovator in biomedical informatics both in education and research.

In education, I served as Director of OHSU's Biomedical Informatics Graduate Program, from its inception in 1996 through 2023. The program has nearly 1000 alumni. I also conceptualized and implemented the first offering of the American Medical Informatics Association (AMIA) 10x10 ("ten by ten") program, which has been completed by more than 3000 individuals since 2005. In addition, I am Editor of the textbook, Health Informatics: Practical Guide, Eighth Edition (Lulu.com, 2022), which is available in print and eBook format and has an associated Web site.

I have also made many contributions in research. My research originally focused in the area of information retrieval (IR, also known as search), where I have authored over 200 scientific papers as well as the book, Information Retrieval: A Biomedical and Health Perspective (Springer, 2020), now in its fourth edition, available from Springer (including SpringerLink) or Amazon, and which has an associated Web site.
