I am an astronomer doing astrophysics, astrochemistry, astrobiology, and planetary science. Currently, I am an Assistant Professor in the School of Earth and Planetary Sciences at NISER Bhubaneswar, India, and a visiting scientist at the NASA Jet Propulsion Laboratory, California Institute of Technology, USA.
I am interested in the physics and chemistry of simple and complex organic molecules in space from interstellar clouds, the birthplaces of stars, through to protoplanetary disks. These organics eventually seed planetary surfaces and atmospheres and play a role in the "Origin of Life."
I use numerical models, single dish telescope observations at (sub-) millimeter/centimeter wavelengths (e.g., NASA DSN, IRAM 30m, GBT, NRO 45m and ARO 12m), interferometric observations at (sub-) millimeter wavelengths (e.g., ALMA and NOEMA), space telescope observations at near, mid and far-infrared wavelengths (JWST NIRSpec, JWST MIRI, Spitzer and Herschel science archive) along with SOFIA observations at Terahertz frequencies for my research.
I am also the co-investigator of a Guaranteed Time Observation (GTO) program of NASA's next flagship astrophysics mission James Webb Space Telescope (JWST) to study physics and chemistry of protostellar binaries in Perseus.
Currently, I am using the interferometric data from the Atacama Large Millimeter/submillimeter Array (ALMA) to study the evolution of volatile molecules in protoplanetary disks with the goal of determining the amount of volatile carbon, nitrogen, and oxygen available to form planets and to compare with the exoplanetary atmospheric compositions derived either from inverse retrieval code or chemical kinetics code.
I am also interested in linking disk models and observations to the origin of comets and have a strong desire to understand the source of the observed organics on them.
I also have a deep interest in the future development (technology) and scientific capabilities of WFIRST, SPICA, OST, SPHEREx, and HabEx mission (together with ground based facilities such as TMT and SKA) to revolutionize our understanding of planetary system formation and complete the census of the outer reaches of the Solar System.
