The Polarization Lab at Duke University is inviting applications for a Postdoctoral Associate to begin immediately. We seek a recent PhD in political science, sociology, social psychology, statistics, computer or information science with an interest in computational social science or data science (broadly defined). This individual will help design, execute, and analyze a series of field experiments on a platform created by the Polarization Lab for scientific research on social media. The ideal candidate will possess advanced knowledge of R and/or Python software, have experience performing statistical analyses and causal inference on large datasets, natural language processing, data management, and experience working with application programming interfaces. The Post-Doctoral Researcher will help supervise graduate students and undergraduate students and work in tandem with a Research Engineer to design and implement new research studies. They will also work with Lab directors to analyze data generated by these studies, write them up as scientific articles, and assist with grant-writing and other public outreach. The postdoc can be affiliated with one (or more) of Statistical Science, Sociology, or Political Science departments at Duke University. There may be an opportunity to teach as well.
