Tianyi Zhou is with Centre for Quantum Computation & Intelligent Systems (QCIS)Faculty of Engineering & ITUniversity of Technology Sydney (UTS) in Australia, supervised by Prof. Dacheng Tao. He received his B.S. degree in automatic control from Beijing Institute of Technology (BIT) in 2008. His research interests are in machine learning, compressed sensing, matrix completion and factorization, dimension reduction and fast optimization algorithms.

Previously, he was a research assistant in School of Computer Eigneering at Nanyang Technological University (NTU) in Singapore, supervised by Prof. Dacheng Tao, between Jan 2009-Jan 2011. Before that, he was a research assistant at Institute of Automation, Chinese Academy of Science (CASIA) in Prof. Tieniu Tan’s group.

His current topics include compressed sensing with quantization, sparse dimension reduction, model selection, manifold learning, multi-label learning, covariance selection, low-rank and sparse matrix decomposition, matrix completion, Nesterov's gradient method and its extensions, fast gradient clustering, low-rank learning, graphical model selection/learning, dual decomposition and non-parametric Bayesian.
