Malik) was an Indian mathematician who specialised in applied mathematics, especially in nonlinear phenomena.
He was awarded in 1983 the Shanti Swarup Bhatnagar Prize for Science and Technology, the highest science award in India, in the mathematical sciences category.
Malik did pioneering work on nonlinear dispersive waves in self-gravitating media, electrohydrodynamics and magnetohydrodynamics.
In particular his theory on nonlinear
breakup of a self-gravitating column has thrown some light on the phenomenon of condensation in astronomical bodies.
His work on nonlinear self-focussing in magnetic fluids is expected to have industrial applications.
