Current Research Interests
My research interests are on theoretical matters related to atoms. These span a wide range of very exciting and challenging research areas. Be it the nature of fundamental interactions or the physics of galaxies or phenomena in condensed matter physics or quantum chaos or precision time keeping, it is of immense value to know atoms to fine detail.

It is interesting and amazing to study how atoms respond to external fields. Depending on the nature of the field and how it is applied, one can have a peek at the inner workings of an atom or collection of atoms. Some of the revelations could be far reaching and of fundamental importance.

My current research interests are:

Future research interests
In the near future I shall continue to work on research projects related to the above topics. As long term undertaking, I have initiated research work on the following topics:
