This is Golam Mortuza Hossain. I am currently an Associate Professor at the Department of Physical Sciences of the Indian Institute of Science Education and Research Kolkata ( IISER Kolkata ).

My Research

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 curved spacetime.

Research Interests

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.

Personal Stuffs

I am married to Nadira and we have a little daughter named Reeha.

Other Interests

Apart from Physics, I have interests in free softwares, in particular those related to computing in Bengali (my native language).

In my free time, I have been experimenting and coding for a free (as in freedom) machine translator for Bengali, Anubadok.

Anubadok translation system relies on a Penn Treebank Tagger for parts of speech tagging. For this purpose, I had to enhance some functionality of Brill's rule-based parts-of-speech tagger. The modified tagger is available as GPoSTTL.
