Primary Teaching Area:Linear Algebra, Complex Analysis, Algebra, Functional Analysis, Advanced Numerical Analysis, Differential & Integral Equations, Ordinary and Partial Differential Equation, Dynamical System, Mathematical Modelling.Research Profile: Dr. Saroj's research involves the use of Differential Equation, Delay Differential Equation and Impulsive Delayed Differential Equation to model the biological, environmental and virological problems taking account of competition of species, age groups, impulsive perturbation etc. and predict their long time behavior using tools like stability, bifurcation. The complex dynamical behavior of the system arising out of these effects is one of the key motive to explore in this studies. Prior to his appointment at South Asian University, He was Assistant Professor in Department of Mathematics in BITS Pilani, Pilani Campus. He has more than four years of teaching experience in teaching various UG and PG courses.
