Research

Do you want to know how the spread of COVID-19 can be predicted by mathematical models?

Have you ever heard of the anti-mosquito technology called “killing mosquitoes with mosquitoes”?

Do you want to know how food quantity and quality affect ecological population trends?

With these interesting questions in mind,

today we take you to the biomathematics research team,

using mathematical language to explain the secrets behind biological phenomena.

Team leader:

XUE Ling, professor and doctoral supervisor of College of Mathematical Sciences, Harbin Engineering University. She is a member of the Biomamathematics Committee of the Chinese Mathematical Society, the Executive director of the Industrial and Applied Mathematics Society of Heilongjiang Province, the deputy director of the Key Laboratory of Engineering and Application of Heilongjiang Province, the editorial board member of Applied Science and Technology Journal, and the guest editor of the journal Frontiers in Physics. In 2013, she received his PhD from Kansas State University, USA. During his PhD, she mainly studied the modeling and analysis of vector-borne infectious diseases on complex networks. From 2014 to 2016, she worked as a postdoctoral researcher in the Department of Mathematics and Center for Mathematical and Computational Science at Tulane University, USA. His co-supervisor was James M.Hyman. From 2016 to 2017, she was jointly funded by the Pacific Mathematical Research Institute of Canada and the Department of Mathematics of the University of Manitoba, Canada, to conduct research on biomamathematics at the Department of Mathematics of the University of Manitoba, Canada, with Julien Arino and Felicia Magpantay; She started to work in Harbin Engineering University in 2016 and was awarded as the young academic backbone of Harbin Engineering University. She is mainly engaged in the research of biomathematics and complex networks. The team consists of 2 professors (Xue Ling and Zhang Jimin), 2 associate professors (Chai Yanyou and Sun Wei), 1 overseas adjunct associate professor and 3 lecturers (Lian Chunbo, Rong Xinmiao and Zhang Yanfen). Two have overseas education, three graduated from 985 universities, and one graduated from double first-class universities. The team is in charge of the National Natural Science Foundation, provincial fund, National Military Science and Technology Commission projects.

The main research direction of the team

The team has been cooperating with outstanding teams in the field from the United States, Canada, Australia, Mexico and other countries to jointly train graduate students. The team has published about 150 SCI papers. The main research directions of the team are as follows:

1. Dynamic complex network

What's the fastest way to arrest an elusive criminal suspect? It turns out that people spend a lot of time to find him out through surveillance video analysis and open investigation. Today, through the dynamics of human behavior in social networks, targets can be quickly targeted. This is actually just a typical application of complex networks, which have a value in every industry. Complex network research is about making the world simple.

2. Prediction and early warning of infectious diseases

In recent years, the prevention and control of emergent infectious diseases has aroused widespread concern in the society. Emergent infectious diseases not only pose a great threat to people's life and health, but also have a serious impact on economic development and social stability. Timely early warning, real-time monitoring and reasonable prediction of emergent infectious diseases are of great practical significance for the prevention and control of infectious diseases.

3. Ecological stoichiometric theory and its application

The main induced mechanism of algal blooms in freshwater aquatic systems was simulated based on ordinary differential equation and partial differential equation, and the important role of water movement, nutrition and light in algal bloom process was elucidated, which provided the necessary theoretical basis and scientific basis for the prediction and control of algal bloom outbreaks in freshwater lakes.

Microscopic planktonic algal cells

Aquatic ecosystem structure map

The global existence and uniqueness of solutions of elliptic equations and parabolic equations are studied, the long-term dynamic behavior of solutions, the branching and stability of solutions, the free boundary problem, the traveling wave solution problem, etc. Qualitative analysis of dynamics of Logistic model, competition and predation model and other models in ecology.

4. Statistics and its application

Statistics is a branch of applied mathematics, mainly through the use of probability theory to establish mathematical models, collect the data of the observed system, quantitative analysis, summary, and then infer and forecast, to provide basis and reference for relevant decisions. The application of statistics is the use of mathematics, the establishment of mathematical models, through the investigation of various data and information to carry out mathematical statistics and analysis, the formation of quantitative conclusions. Statistical analysis is a widely used modern scientific method, which is a relatively scientific, accurate and objective assessment method.
