My research focuses on developing and evaluating methods to assess comparative effectiveness and safety for health care interventions. The great importance of these topics has received increasing recognition in recent years among government funding and regulatory agencies, as well as in the medical community at large. For example, the US Patient Protection and Affordable Care Act of 2010 established the Patient-Centered Outcomes Research Institute to conduct research regarding the benefits and harms of health care treatments for different segments of the population. This new institute's work is to build on the results of $1.1 billion of funding allocated to comparative effectiveness research through the American Recovery and Reinvestment Act of 2009. Additionally, the Prescription Drug User Fee Act (PDUFA) directed the US FDA to significantly increase focus on and funding for post-market safety assessment of drugs and medical devices starting in 2008.

My work concentrates around two key aspects of safety and effectiveness research. My primary area of expertise is research synthesis, or meta-analysis. Research synthesis not only reduces the cost of important discoveries, but is the only practical way to empirically evaluate interventions for diverse and fragile populations. My program in research synthesis has three components: evaluation of randomized trial generalizability, synthesis of data collected with randomized and observational designs, and assessment of treatment effects on rare event outcomes. More recently, I have also been working on the use of genetic biomarkers to improve treatment effectiveness and safety. Through genetic association analyses, modern healthcare can realize the promise of personalized medicine to accurately choose interventions most effective and safe for each individual.
