Prof. Vasudevan's research focuses on studies of 'Guest molecules in Layered and Porous Solids '. More specifically he looks at the physical chemistry aspect of layered, porous and nano-structured host lattices integrated with interesting guest molecules. Such an integration of guest molecule with a layered material leads to novel phenomena and interesting new materials. He studies the interaction and change in properties between host and guest molecules experimentally by using spectroscopic and microscopic studies. Theoretically he does molecular dynamic simulation to help in better understanding of the system. "His research is characterized by rich diversity both in terms of the materials he makes, the studies he carries out, and the applications he targets", says Prof. A. G. Samuelson, one of his peers at the Department of Inorganic and Physical Chemistry, IISc.
