Biography

Yi-Shuai Niu, an Associate Professor of Mathematics at Beijing Institute of Mathematical Sciences and Applications (BIMSA), specialized in Optimization, Scientific Computing, Machine Learning, and Computer Sciences. Before joining BIMSA in October 2023, he was a research fellow at the Hong Kong Polytechnic University (2021-2022); an associate professor at Shanghai Jiao Tong University (2014-2021), where he led the “Optimization and Interdisciplinary Research Group” and double-appointed at the ParisTech Elite Institute of Technology and the School of Mathematical Sciences. His earlier roles include postdoc at the University of Paris 6 (2013-2014) and junior researcher both at the French National Center for Scientific Research (CNRS) and Stanford University (2010-2012). He was also a lecturer at the National Institute of Applied Sciences (INSA) of Rouen (2007-2010) in France, where he earned a Ph.D. in Mathematics-Optimization in 2010 and double Masters in Pure and Applied Mathematics and Genie Mathematics in 2006. His research covers a wide range of applied mathematics, with a spotlight on optimization theory, machine learning, high-performance computing, and software development. His works span various interdisciplinary applications including: machine learning, natural language processing, self-driving car, finance, image processing, turbulent combustion, polymer science, quantum chemistry and computing, and plasma physics. His contributions encompass fundamental research, emphasizing novel algorithms for large-scale nonconvex and nonsmooth problems, and practical implementations, focusing on efficient optimization solvers and scientific computing packages via HPC. He developed more than 36 pieces of software and published about 40 articles in prestigious journals and conferences (including SIAM Journal on Optimization, Journal of Scientific Computing, Combustion and Flames, Applied Mathematics and Computation). He was PI of 6 research grants (including a Key Project of NSFC) and members of 5 joint international research projects. His honors and distinctions include: Beijing Overseas Talent Programs, core member of the Beijing Strategic Scientist Program, the First Prize of the Shanghai Teaching Achievement Award (2017), the First Prize of the Teaching Achievement Award at Shanghai Jiao Tong University (2016 and 2017), as well as 17 awards in the International Mathematical Contest in Modeling (MCM/ICM), including the INFORMS Best Paper Award in 2017.
