Lecturer Intro
Jie Wu received a Ph.D. degree in Mathematics from the University of Rochester and worked as a postdoc at Mathematical Sciences Research Institute (MSRI), University of California, Berkeley. He was a former tenured professor at the Department of Mathematics, National University of Singapore. In December 2021, he joined the Yanqi Lake Beijing Institute of Mathematical Sciences and Applications (BIMSA). His research interests are algebraic topology and applied topology. His main achievements in algebraic topology are to establish the fundamental relations between homotopy groups and the theory of braids, and the fundamental relations between loop spaces and modular representation theory of symmetric groups. In applied topology, he has obtained various important results on topological approaches to data science. Currently, he leads his research team for bi-directional applications of topology aiming to topological foundation of high-order interactions in complex systems, developing algebraic topology of directed graphs and hypergraphs, and applying topological approaches beyond persistent homology to practical problems. He has published more than 100 academic papers in top journals such as “the Journal of American Mathematical Society”, “Proceedings of the National Academy of Sciences of the United States of America”,“Advances in Mathematics”, etc. In 2007, he won the "Singapore National Science Award”. In 2014, his project was funded by the “Overseas Joint Fund of National Natural Science Foundation” (Jieqing B).
