Prof. Chen Xiaojun, Chair Professor of Applied Mathematics and Director of University Research Facility in Big Data Analytics, was elected to the 2023 Class of Fellows of the American Mathematical Society (AMS) for her contributions to mathematical optimization, stochastic variational inequalities and the analysis of nondifferentiable functions.

AMS was founded in 1888 to further the interests of mathematical research and scholarship. Its fellows programme recognizes members who have made outstanding contributions to the creation, exposition, advancement, communication and utilization of mathematics. Prof. Chen is among 39 mathematical scientists from around the world who have been named in the 2023 Class of Fellows.

Prof. Chen’s research interests include stochastic equilibrium problems and nonsmooth, nonconvex optimization. She has published over 90 research papers in top journals of applied mathematics and has been awarded over 20 grants as a principal investigator by the Hong Kong Research Grants Council, the Australian Research Council and the Japan Society for the Promotion of Sciences.

She is a Fellow of the Society of Industrial and Applied Mathematics (SIAM) and serves as area editor/associate editor of seven SCI journals including SIAM Journal on Numerical Analysis and SIAM Journal on Optimization.

Currently, Prof. Chen is also Co-Director of the Chinese Academy of Sciences Academy of Mathematics and Systems Science–PolyU Joint Laboratory of Applied Mathematics. She was Head of the Department of Applied Mathematics between 2013 and 2019.
