Research Summary:

The focus of Dr. Austin's research is on statistical methods for health services and clinical epidemiology research. There are three themes to his program of research:

• propensity-score methods for estimating the effects of treatments, interventions, and exposures using observational data
• survival analysis in the presence of competing risks
• statistical methods for predicting outcomes for patients receiving medical or surgical care.
