Hello, and welcome to my home page. At the top of this page, you can find links to my Vitae, reprints of my published articles, some working papers, and descriptions of ongoing research. I update this page occasionally -- and hope to do so more often -- so please check back soon. 

I am the Mitsui Professor of Political Science at MIT and a Faculty Affiliate at the Institute for Data, Systems, and Society (IDSS) I am a specialist in the fields of political behavior and public opinion with over 25 years of experience in survey design and analysis. For the last decade, I have been studying political rumors and misinformation.

I have won several scholarly awards, received multiple grants from the National Science Foundation, and was a fellow at the Center for Advanced Study in the Behavioral Sciences. I am also the founding director of the MIT Political Experiments Research Lab.  In 2016, I was appointed a John Simon Guggenheim Memorial Foundation Fellow to study how political rumors spread and how they can be effectively debunked.

I have spoken to numerous academic, professional, and public groups about my research, including many regional chapters of the MIT alumni association, attendees at the Newbo Evolve Festival, various divisions at Facebook, Google, Twitter, the American Board of Internal Medicine Foundation, and the American Society for Virology. I have also briefed senior State Department officials, officials at the Department of Homeland Security, the US Department of Defense Strategic Multilayer Assessment program and senior members of the Finnish and Swedish governments about the implications of my research for developing policy strategies to fight misinformation.
