The Language Understanding and Knowledge Acquisition (LUKA) Lab is directed by Dr. Muhao Chen. Our research focuses on robust and accountable machine learning methods for natural language understanding, structured data processing, and knowledge acquisition from unstructured data. We are also interested in knowledge-driven intelligent systems that handle interdisciplinary tasks (for example, biology, medicine, software engineering, and geoinformatics). Our long-term goal is to develop robust, generalizable and minimally supervised knowledge-aware learning systems that help machines understand nature.

We are looking for several new Ph.D. students to join the lab. Prospective students please read this.
