DST-FIST funded Post Graduate Department of Mathematics started functioning in 1980 and was upgraded to a Post Graduate department in 1982. Currently. the department offers the following academic programmes: B.Sc. in Mathematics (3 years), B.Sc. Honours in Mathematics (4 years), B.Sc. Honours with Research in Mathematics (4 years) and M.Sc. in Mathematics (2 years). Department of Mathematics includes six permanent faculty members. Bachelor of Science in Mathematics programme is designed to provide students with a robust foundation in both theoretical and applied mathematics. With a focus on developing critical thinking and problem-solving skills, the programme prepares graduates for a variety of careers in industry, academia, and research. The department offers specialised courses which include cryptography, actuarial mathematics, mathematical modeling, statistics and stochastic processes, data analysis using Python and R. These courses cater to emerging fields and essential mathematical applications ensuring the students are well-equipped for the future. The department has a computational lab with 20 computers, all with high-speed internet access.

The department has nine faculty members who are actively involved in research. Major research areas include number theory and modular forms, Algebraic K-theory, fractal geometry, fixed point theory and operator theory. Certificate courses in Geogebra, Automata and Theory of equations are offered by the department and a Math-Forum named Sinofcos has been functioning since 2013. The forum, started as a discussion platform for TKM students and faculty, has made its mark in academia by conducting activities like PI Day celebrations, Meet the Scholar Program, Faculty Talks, PAL (Peer Assisted Learning), Students’ Talks, Quiz programmes for school students etc. The members of the forum include both regular students of the college and alumni of Sinofcos, consisting of students from other departments of the college. The department also has a good placement record with students obtaining placements in multinational companies like Wipro, Infosys, TCS, Zifo, Federal Bank, and more.
