Our society is globally connected, but language barriers prevent deeper connections and mutual understanding. To break these barriers, my research group works on multilingual natural language processing (NLP) systems that understand and generate human language. Progress in NLP requires advances in machine learning, computer science, and linguistics. We are interested in many basic research problems in these fields.
