I am an Assistant Professor of Computer Science at American University. I develop applied AI/ML approaches to computational social science. These methods address research questions about political elite and non-elite ideology, affective polarization, and hateful and abusive speech and memes. Some recent papers along these research interests include measuring ideology and text scoring.
