Biography

Dr. Cheng Xinyu received a first-class Bachelor's degree in Mathematics from the The Chinese University of Hong Kong in 2015. He received his master's degree and Doctor's degree from the University of British Columbia in 2017 and 2021 respectively. He conducted postdoctoral research at the School of Mathematical Sciences, Fudan University, from 2021 to 2023. He has won the introduction project of the Postdoctoral Researcher International Exchange Program and the Shanghai 'Super Postdoctoral Researcher' incentive program. He took charge of one project of China Postdoctoral Researcher Science Foundation and one special funding project of China Postdoctoral Researcher Science Foundation. Since December 2023, he has worked as a Junior Principal Investigator in Research Institute of Intelligent Complex Systems, Fudan University, devoted to the theory, modeling and cross-application of space-time dynamic equations in complex systems.  He has published 7 academic papers in the top or first-class journals in the relevant field, including Communications in Mathematical Physics, SIAM Journal on Applied Mathematics, Journal of Scientific computing and etc.
