I was born in a small town Malda, West Bengal, India. This town is on the way to Darjeeling from Kolkata. Since childhood, going to the hills of the Himalayas, the Bay of Bengal, or the jungles of Sundarban were our frequent and favorite destinations. This might have a role in my love for travel. I am the single son of my parents. My father worked as Head Clerk in the District Magistrate's office, which is under the State Govt of West Bengal. My mother is working in a Women and Child Welfare scheme under the Central Govt (of India). I have been attracted to astronomy and space for a long time. I was in high school when I got interested and decided that I would pursue my career in astronomy. And my love for astronomy has increased ever since. Apart from research, in my free time, I love to read books, make paintings, do recitations, watch movies, and so on.

Skills & Professional Experiences:
X-ray & UV observations:
I have observed active ultra-fast rotators as the Principal Investigator in X-ray, UV, and optical bands from the AstroSat satellite. Recently four proposals as Principal Investigator (PI) from AstroSat Satellites have been accepted in the Announcement of Opportunity Cycles AO-02, AO-04, and AO-07, and the observations have been carried out recently.
Photometric, spectroscopic, and polarimetric observations of ~135 nights have been performed using 3.6-m ARIES Devasthal Optical Telescope (DOT), 1.3-m ARIES Devasthal Fast Optical Telescope (DFOT), 1.2-m Mount Abu Infra-Red Observatory (MIRO), 1.04-m ARIES Sampurnand Telescope (ST), and 0.9-m MIRA Oliver Observing station (OOS).
Scientific Data Handling:
I can efficiently handle X-ray, UV, & optical data from space-based observatories including XMM-Newton, Swift, Chandra, AstroSat, NICER, MAXI, ROSAT, Suzaku, Kepler, Hipparcos, and other satellites. I also have good expertise in handling optical and IR data, with the experience of dealing with photometric, spectroscopic, and polarimetric data from several ground-based observatories viz. Sampurnanand Telescope, Devasthal Fast Optical Telescope, IUCAA Girawali Observatory Telescope, Goddard Robotic Telescopes, Ege University Observatory Telescopes, Himalayan Chandra Telescope, Very Large Telescope/NACO, Oliver Observing station, ASAS, SuperWASP, etc.
Scientific Packages & tools:
I do programming mostly on Python. Besides this I use different programming languages such as IDL, Unix Shell, Fortran, tcl/tk, IRAF, C++, R, etc.
For X-ray data reduction and analysis I use HEASOFT, FTOOLS, CIAO (for Chandra), SAS (for XMM-Newton) softwares. For optical and IR data reduction I use SCISOFT, IRAF, DAOPHOT, Anaconda packages. For plotting I use Python, Gnuplot, SM, and pgplot. Besides I use other softwares like LaTeX, Windows Office, Open Office, etc.
I have made automatic flare detection algorithms and python code from Kepler data. I also made codes for automatic reduction and analysis of a large amount of X-ray data.
