The Department of Mathematics is engaged in teaching and research in many areas of Pure, Applied and Computational Mathematics. The Department offers M.Sc. (two-year programme) and Ph.D. Degree programmes in Mathematics, and a two-year M.Tech. Degree programme in Industrial Mathematics and Scientific Computing. The outgoing students of the Department are recruited by leading industries through the institute Placement Office. They hold high positions in reputed institutes, universities and companies around the globe.

The core courses for the M.Sc. programme are offered in the first three semesters. These courses include subjects such as Algebra, Discrete Mathematics, Linear Algebra, Ordinary and Partial Differential Equations, Real Analysis, Complex Analysis, Functional Analysis, Topology, Measure and Integration, Probability Theory, Numerical Analysis. In the second year, students can choose electives from a rich menu of subjects such as Computational Fluid Dynamics, Combinatorial Optimization, Commutative Algebra, Fuzzy Sets, Operator Theory, Fixed Point Theory and Applications, Graph Theory, Stochastic Processes and Operations Research. The students can also do a project, which will introduce them to advanced topics and research methodologies. Seminar and viva-voce are also part of the programme.

The Department has 33 faculty members. In addition to teaching and research, they are actively engaged in continuing education and consultancy. Several faculty members have authored books which are used as texts in many universities. Many of them coordinate important projects funded by national agencies/organizations like CSIR, DST, ISRO, DRDO, DAE and NBHM. Many of them are recipients of national and international awards for their teaching and research. Their research areas include Real and Complex Analysis, Functional Analysis, Operator Theory, Harmonic Analysis and Wavelet Theory, Applied Algebra, Commutative Algebra, Algebraic Geometry, Algebraic Topology, Numerical Analysis, Computational Fluid Dynamics, Optimization Theory, Differential Equations, Inverse and Ill-Posed Problems, Mathematical Physics, Fluid Mechanics, Applied Probability and Stochastic Processes, Graph Theory, Fuzzy Sets, Mathematical Logic and Theoretical Computer Science.

The Department is well-equipped with two computer labs meant for research scholars and post-graduate students. Each lab has about 30 systems, high-end servers and workstations. All the machines are connected under institute network system. The Department has a separate library to cater to the needs of our students and faculty.

The Department conducts weekly seminars and invited lectures addressed by visiting mathematicians and faculty from IIT and other institutes. The Department arranges two annual events, namely, the National Symposium on Mathematical Methods and Applications held on 22nd December commemorating the birth anniversary of Indian Mathematical genius Srinivasa Ramanujan and FORAYS - a MATHFEST conducted by students. Besides, the faculty members organize National/International Conferences/ Workshops periodically.
