About Me

I am a PhD graduate from NYU's Wilf Department of Politics and current Postdoctoral Fellow at Vanderbilt's Data Science Institute with 10+ years of wide-ranging research experience in both methods and applications. I specialize in computational methods --with emphasis on NLP, networks and machine learning-- and their application to the study of political polarization and attitude judgments. My research draws in significant ways from multiple disciplines --cognitive science, computer science, linguistics and social psychology-- and has been published (or is forthcoming) in the Journal of Politics, the British Journal of Politics and the Journal of Labor Economics among others. In 2020 I launched Weavio LLC to help researchers collect and extract robust actionable insights from qualitative data at scale using NLP and AI.
