Profile Summary 

My research interests lie broadly within theoretical particle and astro-particle physics and cosmology. The existence of Dark Matter (DM) in our Universe today is well established. Various cosmological [measurements of Cosmic Microwave Background Radiation (CMBR) anisotropy] and astrophysical probes (mass to light ratio estimations in galaxy clusters, galaxy rotation curve, weak and strong gravitational lensing measurements, observation of bullet cluster) indicate the presence of non-luminous, non-baryonic, weakly interacting matter (DM) at different scales. Improved measurements of CMBR anisotropy by WMAP and PLANCK collaborations indicate that DM constitutes about 26% of the energy density of our Universe (assuming the standard model of cosmology).

My focus is in understanding Dark Matter (and various alternative proposals), and probing well-motivated frameworks beyond the Standard Model of Particle Physics (SM), which incorporate a Dark Matter candidate.

Apart from research, I enjoy teaching and interacting with curious minds. If you find any of these topics interesting and would like to know more, or simply would like to have a chat, please feel free to drop an email.

Research Interest :

Theoretical Particle and Astro-particle Physics, Cosmology

More specifically :

1. Dark Matter [Supersymmetric and non-supersymmetric candidates, cosmological and astro-physical signatures and constraints, probing DM properties with CMB, prospects of direct and indirect detection and collider searches in specific models; thermal and various non-thermal production mechanisms]
2. Collider searches for BSM physics [Discriminating between various supersymmetric models and constraining the same, implications for Dark Matter]
3. Inflationary Cosmology and aftermath [Embedding inflaton within a particle physics model; primordial gravitational wave; primordial magnetogenesis; (p)reheating; implications of cosmological data on Dark Matter model building]
