On the morning of November 29th, the 2021 "Famous Teachers' University Lectures" series of lectures co-sponsored by the School of Mathematical Sciences and the Institute of Applied System Analysis of Jiangsu University opened on the cloud as scheduled. The guest speaker invited in this issue is a well-known expert in the field of biological mathematics-Professor Yanni Xiao, deputy dean of the School of Mathematics and Statistics, Xi'an Jiaotong University. More than 120 teachers and students including Professor Shigui Ruan of Miami University, Professor Xiaoli Wang of Southwest University, Professor Bo Zheng of Guangzhou University, Professor Gang Huang of China University of Geosciences, Professor Zhitao Zhang, Professor Jun Wang, and Associate Professor Kaihui Liu of Jiangsu University attended this lecture.

Before the lecture, Dean Zhitao Zhang gave a brief introduction to Professor Yanni Xiao and presided over the lecture.

Professor Yanni Xiao gave a wonderful academic report on the topic of "How and when to lift COVID-19 travel bans? A model/data driven study". The report mainly introduced the mathematical model of the new coronavirus infection under various prevention and control measures. Firstly, she gave a quantitative description of the strengthening and relaxation of control measures and introduced classic infectious disease models. Subsequently, the concept of the SEIR model and diffusion distance driven by prevention and control measures is introduced, and the effect of matching the model with real data is given. Finally, a mathematical model is used to give the optimal unblocking scheme.

Professor Xiao's report is both theoretical and practical, showing the great application of biomathematics in real life, and arousing great interest from teachers and students present.

After the report, Professor Xiao gave patient and detailed answers to the questions that everyone was concerned about. Dean Zhitao Zhang made a concluding speech for this lecture.
