Specific areas of interest include :
The phenomena of squeezing dealing with the reducing of
quantum mechanical uncertainty than that of a minimum
uncertainty state. Its study in atomic system known as
spin squeezing.
The physics of micromaser and microlaser, the one-atom
laser. Study of possibilities of generating Fock states
of radiation fields.
Slow light using multiwave mixing and self induced
transperancy.
The role of quantum mechanics in the conventional
thermodynamics. Its demonstration by adding a
one-atom laser to an Otto cycle engine.
Nonlocality, measurement problem, macroscopic limit, decoherence, Bohmian mechanics micromaser, cavity-QED, tests of foundational issues through quantum optical experiments.
Gauge field theories in 2+1 dimensions with Hopf and Chern-Simons terms, solitonic configurations and fractional spin.
Higher dimensional theories of gravity, inflation, brane cosmology.

Tissue characterization using light scattering methods, in particular,
studies relating to phase function dependence of light propagation in
biotissues, Monte Carlo simulation etc.
Tissue characterization using ultrasound back scattering. The aim here is
to characterize the tissue in terms of properties like density and
compressibility, from the iultrasound backscattering by the tissue constituents
Light scattering from a random dispersion of absorbing/nonabsorbing
particles in an absorbing medium. The particular context here is the scattering
of electromagnetic radiation from coal-water slurries.
