Professor Liqun Qi received his B.S. in Computational Mathematics at Tsinghua University in 1968. his M.S, and Ph.D. degree in Computer Sciences at University of Wisconsin-Madison in 1981 and 1984 respectively. Professor Qi has taught in Tsinghua University, China, University of Wisconsin-Madison, USA, University of New South Wales, Australia, and The City University of Hong Kong.  He is now a Chair Professor at Department of Applied Mathematics, The Hong Kong Polytechnic University.  

Professor Qi has published more than 300 research papers in international journals. He established the superlinear and quadratic convergence theory of the semismooth Newton method, and played a principal role in the development of reformulation methods in optimization. 

Professor Qi's research work has been cited by the researchers around the world. According to the authoritative citation database www.isihighlycited.com in 2003, he was one of the world's most highly cited 345 mathematicians then. He is ranked No. 16 in H-index among 27033 authors of Control and Optimization in the world by Microsoft Academic. Professor Qi is an editor or an associate editor of ten international journals. He has chaired more than fifteen international conferences and workshops held at Australia, Italy, Hong Kong and the Mainland China. In 2005, Professor Qi pioneered the research on eigenvalues for higher order tensors, which now has applications in biomedical engineering, statistical data analysis, spectral hypergraph theory, solid mechanics, quantum mechanics, etc. He has more than110 papers on tensors, published or accepted for publication in international journals. His book ``Tensor Analysis: Spectral Theory and Special Tensors, is published by SIAM in April 2017. Another book ``Tensor Eigenvalues and Their Applications’ will be published by Springer.
