Professor Yonghui Xia is a distinguished professor at Zhejiang Normal University. His research experience in differential equations includes the theory of the Quaternion Differential Equations, Hartman–Grobman linearization and spectra; travelling waves of PDE models; the qualitative theory of ODEs, such as limit cycles and periodic solutions; stability analysis in nonlinear systems; mathematical biology; and neural networks (including continuous, discrete, and impulsive systems). He has published more than 120 journal papers, such as in Proceedings of the American Mathematical Society, Proc. R. Soc. A, Studies in Applied Mathematics, the Journal of Differential Equations, the SIAM Journal of Applied Mathematics, Proc. Edinburg Math. Soc., JMAA, IJBC, NA, etc. His work is ongoing. From 2014 to 2019, he was selected as one of the most cited Chinese researchers for his exceptional research performance in the field of Mathematics (highly cited papers that rank in the top 1% by citations for the field and year in Web of Science), with h-index 26 (Scopus). In 2021, he was selected as one of the top 100,000 scientists in the world in all fields (http://www.globalauthorid.com/WebPortal/EliteOrder).
