Dr. Levy studies how policies in public health, healthcare finance, and health services can improve primary and higher order prevention to improve population health. The principal applications of this overall research agenda are the study of policies to reduce the harms of tobacco use and the design and implementation of policies to improve food choice. In tobacco research, he has assessed public policies to reduce secondhand smoke including smoking bans in multiunit public housing. He also has a secondary research interest in using cost-effectiveness methods to help prioritize resource use and understand competing incentives to adopt alternative policies. His goal is to find effective and efficient strategies to address the leading preventable causes of death.  Dr. Levy is the PI and/or Co-I of several smoking policy related grants including a NHLBI funded project and a Patient Centered Outcomes Research Institute (PCORI) funded project led by Dr. Eden Evins and an NHLBI R01 led by Dr. Rigotti. He also collaborates and with other mentors (Drs. Park, Thorndike, and Winickoff).
