I have been working on two major cosmological puzzles, namely, understanding the mysterious Dark Matter (DM) and dominance of matter over anti-matter. In addition, I work also on 21cm cosmology- a probe of the post CMB dark ages of the universe. Currently my research interests include understanding new production mechanisms and properties of Dark matter within particle physics and modified gravity scenarios. I am one of the authors who proposed a new mechanism to produce right handed neutrino Dark matter (RHiNO) via temperature dependent matter effect which can be tested in neutrino telescopes such as IceCube. I have been working also on models of baryogenesis. In my latest article, I have shown how a gravitational interaction of right handed neutrinos which also leads to successful baryogenesis can be probed by Gravitational waves (GWs)--particularly with pulsar timing arrays (PTA) as well as neutrino-less double beta decay experiments.  

In the upcoming two years, I wish to work on Gravitational wave and multi-messenger probes of DM and baryogenesis models within particle physics as well modified gravity scenarios. I will focus also on testable scenarios (within the context of multi-frequency GW astronomy) of primordial black hole (PBH) dark matter (as well as baryogenesis from PBH) and physics of ultra-light particles. Please feel free to drop a message should you envisage a collaboration.
