Dr. Miller is an internationally recognized expert on artificial intelligence in medicine, computer-assisted diagnosis and clinical information systems.

Over the past decade, Vanderbilt University Medical Center has developed and implemented a new approach to care provider order entry. Key components have included: a "clinical informatics" team approach in which clinicians build and evolve the system for clinicians; creating a decision-making environment for the clinician where the right information is "one click away" and the system writes orders for the end-user as a result of higher-level interactions (rather than the clinicians directly typing what becomes verbatim legible orders); continuous engagement of end-users in ongoing rapid prototyping and evolution efforts; and, institutional involvement in knowledge acquisition and maintenance, as well as fostering "best practices" through system enhancements. Preliminary evaluations have demonstrated beneficial impact on quality of care, educational resource utilization, and institutional resource utilization.
