I have the following research interests:

Molecular Design, Chemical Biology, Bioorganic & Biomimetic Chemistry, Membrane Biology/ Biophysics, and Supramolecular Materials.

1. Molecular Design:

My group is involved in the design and synthesis of the following types of molecules or molecular/supramolecular entities.

  1. Lipids and their analogues.
  2. Dendrimers and cascade molecules.
  3. Self-assembled layered molecules.
  4. Nucleic acid binding/modifying molecules.
  5. Transition metal based catalysts for sequence-neutral/-specific DNA and Protein modification.
  6. Micellar catalysts for acyl transfer, hydrolytic and oxidation reactions in water.

2. Chemical Biology, Bioorganic & Biomimetic Chemistry, Membrane Biology/ Biophysics:

We are currently dealing with the following types problems in these areas.

  1. Membrane Formation and Assembly.
  2. Molecular Mechanism of Drug action on DNA.
  3. Protein-DNA interactions.
  4. Activation of ambient oxygen species.
  5. Phospholipase action.
  6. Mechanism of Gene Transfer.

3. Supramolecular Materials:

  1. New Gelators
  2. Novel Surfactants
  3. Materials with Tribological properties
  4. Design of Porous solids
