Collaborations:

Graduate students who are working for their doctoral thesis  in our group.

I also have ongoing collaborations with P. A. Sreeram and S. Dattagupta  of our Centre.

Some of my colleagues from other Institutes with whom I continue to have extensive collaborations are.

I am part of the  Soft Condensed Matter Physics  group of  our Centre.

Research Interests:

My interests are in condensed matter physics, especially materials (both hard and soft) and statistical mechanics.  A pdf version of my vitae  (which is updated occasionally !) is available for download. For the last few years I have been mainly working on:
