General relativity is an amazingly successful theory of gravitation.
However, it predicts the existence of singularities in
regions of extreme densities where it becomes unreliable. It is believed
that a suitable reconciliation of general relativity with
quantum theory, another tenet of modern physics, is needed
to address this issue. The quest for a `quantum theory of
gravity' which is expected to supersede general relativity in
describing physics near extreme gravitational situations has led to several
- My Research Interests:
One of my main research interests concerns primarily 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
The quantization method that is used in LQG, is often referred as
polymer or loop quantization. One of my recent 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.
