General relativity is an amazingly successful theory of gravitation.
However, it predicts existence of singularities in
regions of extreme densities where it becomes unreliable. It is believed
that a suitable reconciliation of general relativity with
quantum field theory, another tenet of modern physics, is needed
to address this issue. However, even before the effects of `quantum theory of
gravity' become dominant, there would be regime where one would need to understand well
the implications of the quantum field theory in classical
One of my current research interests is to explore the effects of the general relativity and
the quantum field theory for compact astrophysical objects such as black holes, neutron stars
and white dwarfs near their mass limits. Here one would need to apply the tools of quantum
field theory in the classical curved spacetime.
My other research interests concern in the field of the so-called
loop quantum cosmology (LQC) which is a mini-superspace approach using techniques
of loop quantum gravity (LQG), a candidate quantum gravity theory.
The quantization method that is used in LQG, is often referred as
polymer or loop quantization. One of my interests is to study the
physical implications of polymer quantization of matter fields.
Apart from the quantum aspects, I am interested in studying the different
classical aspects of modern cosmology.
