I am currently a Professor of Medicine at the University of Michigan Medical School and the Associate Director for Analytic and Information Resources at the VA Center for Practice Management and Outcomes Research in Ann Arbor as well as a member of the UM Institute for Healthcare Policy and Innovation.

I work on measuring and improving quality of care in the complex patient. I am interested in the methodological and practical issues in measuring and profiling quality of care and how the ability to measure quality may affect popular policy initiatives to identify and reduce medical errors or set up pay for performance systems. My projects have focused on the adequacy of risk adjustment, social and economic factors predicting utilization, as well as the patient, provider and organizational influences on performance measurement and indicators. I am a core faculty member in the National Clinical Scholars Program at the University of Michigan (formerly the Robert Wood Johnson Clinical Scholars program) where I teach advanced analytic methods and I spend a significant amount of time on research mentoring and teaching research trainees.
