Lirui Feng, PhD Candidate, University of Science and Technology of China, China

Biography: Lirui Feng is currently in his final year of his combined masters/Ph.D. program at USTC, which usually lasts for 5 years. In 2014, he came to York U under the supervision of Professor Jianhong Wu via the Jointed Educational Plan and began to systematical learn about delay equations and conduct research on traveling wave of reaction-diffusion equations with non-local delay. Now, we have abstracted it to a discrete semi-system and gotten the threshold dynamics. Now, this year maybe is the last year of my PHD study, and there is a long road in my academic career in mathematics and its application. Therefore, I would like to use an ancient Chinese poem line to express my aspirations: “路漫漫其修远兮,吾将上下而求索”.

Research Interests: Dynamics of semi-flow with preserving order induced by cone of high rank, traveling waves of reaction-diffusion equations with delay, and dynamical structure of negative feedback systems with delay.
