Dr. Dennis Yang Liu's research interests include cognitive science, machine learning, applied mathematics, as well as their applications in brain signal processing, high-dimensional data mining, and multimedia content analysis. As a key member and coordinator of cognitive computing lab, he will help with the daily operations of the lab, maintain the lab instruments, and conduct research on exploring the computational basis of human learning via mathematical modeling.

Dr. Liu is a postdoctoral research fellow in the Department of Computing at the Hong Kong Polytechnic University. He received his Ph.D. from the same department in 2011. After that, he spent one year as a postdoctoral research associate in the Department of Statistics at Yale University. Dr. Liu has published more than thirty papers on top journals such as IEEE Trans. Neural Networks and NeuroImage, and top conferences such as SIGMM and AAAI. His paper "Bidirectional visible neighborhood preserving embedding" received the Best Student Paper Award in ACM ICIMCS 2009. During his Ph.D. study, he visited the Robotics Institute at Carnegie Mellon University for half a year.
