Welcome!

I am an Assistant Professor in Computational Social Science at Georgetown University’s McCourt School of Public Policy and a faculty affiliated with the Massive Data Institute. Before joining Georgetown, I was a Postdoctoral Fellow at NYU’s Center for Social Media and Politics, where I remain a Faculty Research Affiliate. Previously, I received my Ph.D. in Political Science from the University of Maryland, College Park, and worked as a Misinformation Researcher at @Twitter.

My research deals with substantive issues on politics and social media, focusing on topics such as content activation and propagation, misinformation, and polarization on social media platforms. I am mostly interested in pursuing a comparative approach to these issues, paying special attention to Global South countries. Methodologically, I am interested in causal inference problems, online field and survey experiments, network models to deal with large volumes of data, and applications of natural language processing to social science problems.

My recent work was awarded a large research grant from the Tech & Public Policy program at Georgetown’s McCourt School to conduct multi-country field experiments focusing on the effects of misinformation exposure through social media messaging apps on beliefs for misinformation and political attitudes in the Global South. In addition, I am working on a book project with Natalia Aruguete and Ernesto Calvo titled News Sharing, Content Activation and Perceptions of Polarization on Social Media

My research has been published at the Journal of Communication, Comparative Political Studies, PLOS ONE, International Journal of Press/Politics, Electoral Studies, among other influential academic journals.
