The department is committed to excellence in undergraduate and graduate training as well as in research and scholarship in pure and applied mathematics. Additionally, we serve the entire student population at the National Cheng Kung University by providing required courses in Mathematics. The Department population includes approximately 60 graduate students, over 240 undergraduate majors, and numerous students completing minors. Our faculty conducts active research in a broad range of areas, from algebra, analysis, and geometry to numerical analysis and scientific computing, operation research, probability and statistics. The department's faculty includes a University Distinguished Professor, and recipients of national awards. Over the 2 years, a large percentage of the faculty has been awarded grants and contracts from external funding agencies, with total awards averaging about NT$14.7 million per year. The commitment in both teaching and research is also recognized by the QS (Quacquarelli Symonds) World University Ranking. In 2012, 2013, the department is ranked in the top 51-100, and in 2014 the department is ranked in the top 101-150 in the QS World University Ranking by Subject-Mathematics.

During the academic year we hold a weekly department colloquium and a number of research seminars. Also, we sponsor or organize several regular workshops, or conferences each year on topics including algebra, geometry, numerical computation, operation research, or partial differential equations.

The department actively promotes mathematics to the broader community through a variety of activities, including organizing a series of courses and Math Camps activities for high school students and teachers.
