2. Computational mathematics. Research interests: numerical methods of engineering problems, numerical methods of evolution equations and dynamic systems, numerical approximation and digital image processing, computer graphics and computer software, mathematical problems in optics and electromagnetism, etc.
3. Probability statistics. It is a rapidly developing discipline in this century, which studies the essence and inherent regularity of various random phenomena in natural science, social science and other disciplines, as well as the scientific comprehensive processing and statistical inference methods of various data. With the continuous improvement of the scale, complexity and accuracy of various systems in human society and the extensive use of computers, probability statistics will become more and more important.
4. Applied mathematics. Applied mathematics is mainly used in two fields. One is a computer. With the rapid development of computer, a large number of software engineers who understand mathematics are needed to develop the corresponding database. The second is economics, many of which need very professional mathematics to analyze. Many related courses of applied mathematics are designed on the basis of economic examples.
