I study active galactic nuclei using multi-wavelength data, especially at radio wavelengths. I use telescopes like the GMRT, LOFAR, JVLA and IRAM along with large scale optical surveys like SDSS to study AGNs. My research interests extend to galaxy clusters, cosmology and exoplanets.

Giant radio galaxies, which harbour active supermassive black holes, are the single largest astrophysical objects known in the Universe. Our studies under project ‘SAGAN’ probes regions of GRGs from few parsecs to megaparsecs. We have discovered more than 400 new giants, doubling its population.
