The group pursues fundamental theoretical
studies in different areas of physical chemistry/chemical physics.
Because of the academic freedom we enjoy at the Indian Institute of Science
in pursuing our research goal, we have almost always explored problems
from very basic point and often studied unusual problems.
Our previous important works ...
- theoretical studies on the solvent effects on electron
transfer reactions,
- development of microscopic theories of solvation dynamics
and orientational relaxation in polar and non-polar solvents,
- microscopic theories of ionic conductivity in electrolyte
solution,
- development of a phenomenological theory of dynamics of
water at surfaces of biological interest (we coined the term
"biological water" which has later been used by many),
- theorietical investigation of protein folding by using
simple minimalistic models which we developed ourselves,
- relaxation in model supercooled liquids and non-ideal
composition dependence in binary mixtures,
- study of the effects of molecular asymmetry in giving rise
to macroscopic chirality,
- anomalous vibrational phase relaxation of nitrogen near
its gas-liquid critical point, among others.
More recently we have studied ...
- dynamics of liquid crystals and explored the analogy
between supercooled liquids and liquid crystals near isotropic-nematic
phase transition from an energy landscape perspective,
- the free energy surface for gas-liquid nucleation in
deeply supercooled regime (near its spinodal decomposition),
- both thermodynamic and dynamic properties of water in the
major and minor grooves of DNA,
- anomalous composition dependence of vibrational relaxation
in binary mixtures,
- Development of a new orientation dependent potential of
mean force between amino acid residues by using the information from
protein data bank,
- Forster energy transfer between donor-acceptor systems
where
- both are dye molecules,
- one dye and another nano metal particle,
- both nano metal particles
- molecular theory of intercalation of a drug into the DNA.
Many of the papers published from our group over the last two decades have/had a wide impact both
in India and abroad. While papers have been cited more than 8000 times, H-index stands at 46.
Collaborators ...
In our research we closely collaborate
both with experimentalists and theoreticians. Our present and past
collaborators include professors Paul Barbara, Kankan Bhattacharyya,
Irene Burghardt, Amalendu Chandra, Michael Fayer, Graham Fleming, Casey
Hynes, Mark Maroncelli, Ed Castner, Peter Rossky, Peter Wolynes, Ahmed
Zewail, among others.
