Dynamics and evolution of clusters of galaxies, groups and early-type galaxies using multi-wavelength observations. The broad areas of interest include:
• Thermodynamics of clusters, groups and giant ellipticals and effect of non-gravitational processes.
• Central AGN feedback mechanism in clusters, groups and giant ellipticals.
• Cold gas in giant ellipticals: Origin and its role in AGN feedback cycle.
• Central metallicity drops in clusters and groups of galaxies.
• Scaling relations in clusters, groups and ellipticals.
• Development of new statistical analysis techniques for analyzing X-ray emission from clusters, groups and giant ellipticals using Bayesian analysis, MCMC.
• Substructures and mergers in galaxy clusters.
• Large-scale radio emission from clusters and its connection with mergers.

• Post-Doctoral Fellow in the Lendület Hot Universe Research Group, Eötvös Loránd University (Budapest, Hungary) with Dr. Norbert Werner from Nov. 2016 to present.
• National Post-Doctoral Fellow at the Department of Physics, Indian Institute of Science (Bangalore) with Dr. Prateek Sharma from August 2016 to Oct. 2016.
