Major research programs of the group are focused in two areas of organic chemistry and synthesis, namely, carbohydrates and dendrimers.

In carbohydrates, on-going research pertains to:

• Synthesis of natural and un-natural target sugar molecules;
• Synthesis and studies of oligosaccharides and glycolipids;
• Biochemical and biophysical studies of carbohydrate-protein interactions.

In the area of macromolecular dendrimers, the research activities are on:

• Synthesis of poly(ether imine) and poly(alkyl aryl ether) dendrimers;
• Organometallic catalysis using multivalent dendritic catalysts;
• Grafting of dendrons on to one-dimensional polymers and physical studies.
