Emmett Keeler is a senior mathematician at the RAND Corporation, and a professor at the Pardee RAND Graduate School.  He has conducted technical analyses for studies evaluating quality improvement interventions, insurance design, cost-effectiveness, and quality-of-care statistics.

In the RAND Health Insurance Experiment, Keeler assessed the effects of alternative insurance plans on physiological health and developed the episode-of-treatment approach to analyze use. He also led the analysis of physiological outcomes for that study. Keeler was the lead technical analyst in the Prospective Payment System Quality of Care evaluation, addressing ways to risk-adjust outcomes and investigating the relationship between explicit, implicit, and outcome-based measures of hospital quality.

His recent projects include an investigation of the cost-effectiveness of lung cancer screening and making the business case in quality improvement. Three of his over 170 published papers have been selected as the article of their respective years by the Academy for Health Services Research and Health Policy and won their Distinguished Investigator Award. Keeler is an elected member of the National Academy of Medicine of the National Academy of Sciences.

Keeler received his Ph.D. in mathematics from Harvard University.
