He was awarded in 1985 the Shanti Swarup Bhatnagar Prize for Science and Technology, the highest science award in India, in the mathematical sciences category.

Prof. Parthasarathy is an expert in representation theory of semisimple Lie groups. His initial work was on the realization of the so-called discrete series of representations of a semisimple Lie group in the space of Dirac Spinors. He made considerable progress in many central problems in representation theory. His work on the resolution of the Blattner's conjecture and the question of unitarisability of certain highest weight modules are significant contributions to this area in mathematics.^[1]
