Prof. Misra's research interests are in high energy astrophysics which includes accretion disk theory, study of spectral and timing properties of X-ray binaries, ultra-luminous X-ray sources, large-scale radio/X-ray jets of AGN and, lately, gamma-ray bursts. His research involves theoretical modeling as well as X-ray data analysis and interpretation. Prof. Misra is also interested in cross-disciplinary studies like non-linear dynamics of astrophysical systems, non-linear time series analysis and statistical classificiation schemes of astrophysical sources.

Prof. Kembhavi's interests are in normal and active galaxies, quasars, pulsars and so on. He is presently working on the morphology of galaxies using ground-based and space data at optical and near-infrared wavelengths, with special attention to lenticulars and luminous compact galaxies. Prof. Kembhavi also works on warm absorbers in active galaxies. He is the PI of the Virtual Observatory - India project, through which he and his collaborators develop applications for virtual observatories.
Neeraj Gupta's research focuses on interstellar medium of galaxies. He is involved in various observational projects with current and upcoming radio telescopes to trace the evolution of cold atomic and molecular gas content of galaxies using absorption lines. He is co-PI of the MeerKAT Absorption Line Survey (MALS), and is interested in observational techniques relevant to large blind searches of absorption lines at radio wavelengths.

Ranjan Gupta
Prof. Gupta's research interests cover three areas: 1) artificial neural networks (ANNs), 2) interstellar dust and 3) astronomical instrumentation. Prof. Gupta has used ANNs to classify stellar spectra and to extract fundamental stellar atmospheric parameters. He has also modelled interstellar and cometary dust by using porous non-spherical composite grains, and has developed astronomical instruments such as photometers, spectrometers and polarimeters in the optical and near-infrared regions.
