Research Focus

​The Signal Processing and Computational Biology Group is an inter-disciplinary theoretical and computational research group in the Department of Electronic and Computer Engineering at The Hong Kong University of Science and Technology (HKUST). We focus on the development of high dimensional (Big Data) statistical signal processing and machine learning methods, and their diverse applications including communication, robust estimation, computational biology, and financial engineering. Our group is also focused on the theory and applications of random matrices.
