Research Activities


Our current research interests are: Designing new and novel Super Organic bases; Morphology of Ionic Solids; Novel sensors for anions, cations and neutral molecules; Ligand binding studies with DNA; Acetylcholinessterase (AChE): Conformations, Dynamics, Hydrolysis and the Therapeutic Pharmacophores; Structural-Activity relationships in Organic and Inorganic systems. Designing Pores and Channels by assembly of cyclic peptides. We do collaborate with experimental chemists to design and synthesize the molecules/systems of immediate interest.
