Dr. Yang Xu, is currently an Associate Researcher （Researcher）at the Department of Computer Science and Engineering, Southern University of Science and Technology (SUSTech) in China. He received a Ph.D in Information Sciences and Technology from The Pennsylvania State University, USA. Before joining SUSTech, he worked as Assistant Professor at the Department of Computer Science, San Diego State University in the United States. Currently he is the PI of Computational Linguistics and Consciousness Sciences Lab (CLCS) and his research interests include Computational Linguistics, Artificial Intelligence, Cognitive Science, and psycholinguistics.  

Our lab is actively recruiting self-motivated graduate and undergraduate students (post-docs as well). You are more than welcome to send your resume to xuyang@sustech.edu.cn
