I'm currently an assistant professor at Cheriton R. Computer Science School at University of Waterloo and Vector Institute. My research interest covers natural language processing, deep learning, knowledge representation and reasoning. Specifically, I aim at developing models that can ground and reason over external world knowledge to understand human language and communicate with humans. I am also interested in multi-modal problems like visual question answering and captioning. I publish and serve as program committee in ACL, NAACL, EMNLP, ICLR, NeurIPS, etc. I received the WACV best-student paper honorable mention in 2021. I also received outstanding dissertation award from UCSB in June 2021. I serve as Senior Program Committee for AAAI and Area Chair for EMNLP and AACL. I'm always looking for talented and self-motivated students. You can drop me an email to demonstrate your interest, but the final decision won't be made until I see all the applications in the system after the official deadline.
