What can statistical text analysis tell us about society? I develop practical and scientifically rigorous text mining methods that can help answer social science questions.

I'm generally interested in machine learning and natural language processing, especially when informed by or applied to areas like political science or sociolinguistics. My work often uses text data from news and social media.

I'm a 5th year Machine Learning Ph.D. student at Carnegie Mellon University (CMU)'s School of Computer Science, in Noah's ARK research group.

I have also been a Visiting Fellow at Harvard IQSS, and an intern on the Facebook Data Science team. Before grad school, I worked on crowdsourced annotations at CrowdFlower / Dolores Labs, as well as "semantic" search at Powerset. I was an undergrad at Stanford with a BS/MS in Symbolic Systems (cognitive science or so).
