Research Interest (s) : I am a theoretical astrophysicist with primary research interests in astrophysical turbulence and the origin and evolution of astrophysical magnetic fields. This field of research is being increasingly recognised as a domain where progress is essential to understand broader astrophysical phenomena such as star formation, galaxy formation and large-scale structure, and the evolution of the early Universe. In recent times, the focus of my research has been on probing observational signatures of turbulent dynamos in the ISM of young galaxies and galaxy clusters. To this end, I use a variety of techniques ranging from semi-analytical methods to computer simulations to address my science goals. Currently, I am interested in problems that can offer insights as to what can be observed with next generation radio telescopes and how to perform meaningful comparison between theoretical predictions and observations. I am also an Associate Member of the SKA Science Working Group (SWG) on ‘Cosmic Magnetism’. My other interests lie in primordial star formation and numerical methods for astrophysical fluid flows.
