Probing the physics of Seyfert galaxies: Contributed to the radio investigation of 127 Seyfert galaxies in the local universe selected to study the extended emission-line regions and interactions with the host galaxy. Cataloged the radio data and processed radio images using AIPs. Correlated the radio structure with the emission-line structures.

X-ray and Radio study of 3C219: Studied radio interferometry and learned AIPS to make radio images of galaxies like 3C19, 3C295 , 3C313 , 3C234 and 3C219 using VLA archive data. Studied interaction of radio galaxy 3C219 with the hot environment. Using CIAO, analysed the temperature of the gas in the region close to the core and lobes of 3C219.

Calculating Chandrasekhar limit for white dwarfs and neutron stars: Studied the equation governing their stability under the inward gravitational collapse and the outward degenerate pressure in white dwarf and neutron star. Numerically verified the Chandrasekhar Limit ( 1.44 M⊙) for white dwarfs and estimated the mass limit and proton fraction for neutron stars.

Large N expansion in quantum mechanics: Theoretical project to generalize the Schrodinger equation to N-dimensional space. Established that in large N-limit, around the minimum of potential, N-dimensional Schrodinger equation boils down to perturbed harmonic oscillator equation. Also studied large N-scheme in relativistic domain.
