I do research to learn what works to improve human health. My collaborators and I design analyses of healthcare databases, epidemiologic studies, and randomized trials. We generate and analyze data to identify better strategies for the treatment and prevention of both infectious and noninfectious diseases. I serve as
- Principal Investigator of the HIV-CAUSAL Collaboration, a multinational consortia of prospective studies from Europe and the Americas. We conduct comparative effectiveness research for the treatment of persons with HIV.
- Co-Director of the Laboratory for Early Psychosis (LEAP) Center, a joint collaboration with McLean Hospital and the Massachusetts General Hospital. Our goal is to better understand the clinical course and care options for individuals with first episode psychosis.
- Co-Director of the VA-CAUSAL Methods Core, a causal inference research initiative within the Veterans Health Administration to help transform the VA into a learning health system that expedites the translation of research into practice and supports decision-making by patients, clinicians, and other stakeholders.
Causal inference from observational data can be viewed as an attempt to emulate a (hypothetical) randomized trial—the target trial. You can read this or this for an introduction to the concept of target trial.

If you prefer to listen to me in person, I plan to participate in these scientific meetings.
My teaching is focused on how to generate, analyze, and interpret data to guide health policy and clinical decisions. I teach causal inference methodology at the Harvard T.H. Chan School of Public Health, and clinical epidemiology at the Harvard-MIT Division of Health Sciences and Technology. For more info about my teaching, click here.
