The Department of Applied Mathematics came into existence with the inception of Institute of Armament Studies in 1953 as Faculty of Applied Mathematics. The faculty constituted of three departments: (1) Applied Mathematics (2) Ballistics (3) Statistics. In 1991 the three departments merged into one and named it as Department of Applied Mathematics. The department is offering two MTech programmes in Data Science and Modelling & Simulation and one MSc programme in Data Science.  The faculty of Department of Applied Mathematics has been actively involved in the research in different fields of applied mathematics such as Numerical Solution to PDEs, Optimization, Statistics, Probability, Neural Network, Fuzzy Logic and Genetic Algorithm, Parallel Computing, Cryptography and Machine Learning, Deep Learning, Medical Imaging, Digital Image processing, ballistics, flight dynamics, hydro-dynamics, hydro-ballistics, etc. The Department of Applied Mathematics has dedicated classrooms for all programmes equipped with state-of-the-art teaching facilities and seating arrangement. All faculty in the department are doctorates from prestigious institutes from India and abroad with expertise in the area of Modelling & Simulation, Computer Vision, Heat and Mass transfer, Fluid Dynamics, Numerical Analysis, Machine Learning, Statistical Analysis, Data Analytics, Deep Learning, Finite Element Methods, Fictious Domain Methods, Domain Decomposition Methods, Finite Difference Methods, Federated Learning, Responsible AI, Continuial Learning, High Performance Computing, Distributed Learning, Digital Image & Signal Processing, Medical Imaging, Computational Instrumentation, Prognostics and Health Management, et
