As a researcher, Prof. Ramakrishnan has developed several new strategies for the synthesis of highly branched soluble polymers and provided a fundamental understanding of structure-property correlation of the relatively new class of polymers namely, ‘hyperbranched polymers’ and strategies to control and examine conformation of synthetic polymers in solution using weak intra-chain inter-segment interactions, such as charge-transfer interactions, metal-ion coordination, solvophobic exclusion etc. Further, immiscibility-driven self-segregation in suitably designed amphiphilic graft copolymers was shown to be an excellent strategy for folding of polymer chains, which in turn led to morphological control in the solid state, thereby providing a bridge to the ‘molecular to bulk’ organizational transition in polymeric systems. He has moreover, developed novel methods for control of conjugation length in an important class of polymers, namely MEHPPV, and thereby demonstrated tuning of the emission colour from these potentially useful materials that could be used in polymeric LEDs.
Prof. Ramakrishnan was bestowed a Silver Medal by IIT Bombay for his performance in M.Sc. programme, and later went on to receive many prestigious awards like S S Bhatnagar Prize; CRSI Silver Medal; Fellow of the Indian Academy of Sciences; DAE-Outstanding Investigator Award, J C Bose Fellow, Associate Editor, Chemical Communications (RSC); Editorial Board member, Macromolecules, ACS Macro Letters and Polymer Chemistry (RSC), to mention some.
In his spare time he likes reading, listening to music, going for long walks and nature trails.
