Mathematics is the language of science. It forms the foundation for various disciplines, such as artificial intelligence, computer science, data science, economics, engineering, physics, and even social sciences. Learning mathematics develops our ability of logical reasoning, precision, critical thinking, such that we can organize and analyze complex information, tackle complex problems in many different areas of your life and career. The programme provides students with a strong background of mathematical theory, skills and tools for mathematical modelling, scientific computation and technical computer software. Our graduates are in high demand in many sectors, including finance, technology, education, etc.. 

The Department specialises in applied and computational mathematics. Undergraduate teaching is backed up by extensive research on a wide range of topics. This places us in close contact with many modern uses of mathematics. Our programme is both relevant and up-to-date.

We are proud of our academic staff, many of whom are internationally renowned scholars. For example, Professor Philippe G. Ciarlet, member of the French Academy of Sciences and of seven other academies, was Chair Professor of the Department until August 2011. He joined the office of the College of Science and Engineering in September 2011 as University Distinguished Professor. Professor Ciarlet has received numerous distinctions, among which a Grand Prize of the French Academy of Sciences and an Alexander von Humboldt Research Award.

Professor Ciarlet is currently Emeritus Professor of the Department, and Senior Fellow in the Institute for Advanced Study of City University of Hong Kong.
