My research brings together natural language processing (NLP), privacy, and computational social science. I direct the Human Language Technologies Lab at Penn State.
I am interested in solving problems to enable computers to do meaningful work with large volumes of natural language text. My lab develops new methods for NLP and applies them to a variety of domains. I am particularly interested in breaking down technology's "walls of text", i.e., situations where a human user or decision-maker is expected to consume a large quantity of text to take action while lacking sufficient resources (time, expertise) to properly understand what they have been given. I have applied this paradigm to a variety of domains including privacy policies, scholarly manuscripts, social media data, speech transcripts, and emails. I am always interested in new problems involving text data to collaborate on.
