During the early-1970s, for my doctoral dissertation, I was principal developer of the clinical expert system known as MYCIN. After a pause for internal medicine house-staff training at Harvard and Stanford between 1976 and 1979, I joined the Stanford internal medicine faculty where I directed a research program in biomedical informatics. My interests include the broad range of issues related to integrated decision-support systems and their effective implementation. In the early 1980s, I worked to create the Stanford degree program in biomedical informatics. From 1995-1999, I served as Associate Dean for Information Resources and Technology at Stanford University School of Medicine. I then moved to Columbia University, where I served as Professor and Chair of the Department of Biomedical Informatics from January 2000 to March 2007. At that time I moved to Arizona to become the founding dean of the Phoenix campus of the University of Arizona's College of Medicine. I stepped down from that role in May 2008 and, in January 2009, transitioned to a primary academic appointment as Professor of Biomedical Informatics at Arizona State University. In July 2009, I succeeded Dr. Don E. Detmer as President and CEO of AMIA, the professional association for informatics in health care and biomedicine. In November 2009 I left Arizona to assume a part-time faculty position in the School of Biomedical Informatics at the University of Texas Health Science Center in Houston. I then moved to New York in October 2011 to return to the faculty as an adjunct professor in the Department of Biomedical Informatics at Columbia University. I completed my term as AMIA President on March 31, 2012 and on April 1st assumed a 5-year position as Scholar in Residence at the New York Academy of Medicine. My wife and I maintain our primary residence in New York City, although we also have a home in Phoenix, AZ. We spend several months per year there as part-time faculty at Arizona State University, where we are both professors in the Department of Biomedical Informatics and I also serve as Senior Advisor to the Dean in the College of Health Solutions. I also joined the faculty at Weill Cornell Medical College as an adjunct professor in July 2013.
My publications through the end of the 1990s are summarized on the Stanford Center for Biomedical Informatics Research site, on ResearchGate, and in my Curriculum Vitae. Books include:
