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. Previously, I received my Ph.D. in Political Science from the University of Maryland, College Park, where I am still a faculty affiliated with the iLCSS 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 research has been published at the Journal of Communication, Comparative Political Studies, Nature Scientific Reports, International Journal of Press/Politics, and PLOS ONE, among other influential academic journals. My research has been awarded with grants from Project Liberty Institute, Tech & Public Policy Initiative at Georgetown, and EGAP, and recognized as the 2024 APSA’s Paul Lazarsfeld Best Paper Award and Best Paper Award in Internet, Technology and Politics, the Best Paper in Political Behavior in the 2024 Brazilian Political Science Association Conference, and the 2022 Mario Fuks Award for the best paper presented in the Political Behavior Section in the Brazilian Political Science Political.

Some of my current projects are a large-scale collaborative global social media deactivation study, a set of multimedia deactivation experiments on WhatsApp in Mexico, South Africa, and India, developing a large-scale panel connecting US voter files with their Twitter accounts, a field study investigating recommendation systems and censorship in Chinese social media, and field experiment increasing users’ exposure to fact-checking accounts on Twitter. I am also working on a book project with Natalia Aruguete and Ernesto Calvo titled News Sharing, Content Activation and Perceptions of Polarization on Social Media
