I am a faculty member in the department of Physics at IISc Bangalore. Earlier I was a postdoctoral researcher in the Astronomy department and
the Theoretical Astrophysics Center at
UC, Berkeley. I completed my graduate studies in the
Plasma Physics program,
department of Astrophysical Sciences at
Princeton University . Before that I was an undergraduate
student at the Indian Institute of Technology, Bombay .
I am very happy to talk to graduate (PhD and integrated PhD) students and other researchers working in my areas of interest. If you are interested in visiting our astro group at IISc please contact me at:

Please write to me with a short research proposal that combines our research interests if you wish to join the group as a postdoc. IISc has recently started the Raman postdoc fellowship.
Presently I am actively working on all aspects of the circumgalactic medium (CGM), the diffuse medium around Milky-Way like galaxies that contains majority of the halo baryons. Here is a review article accessible to physics undergraduates on multiphase gas in and around the circumgalactic/intracluster medium. We use high-resolution idealized simulations, complementary to the cosmological galaxy formation simulations that generally do not have a high enough resolution to faithfully simulate the multiphase CGM. I have also worked on important astrophysical processes such as accretion, collisionless plasmas, cosmic rays, turbulence, non-thermal emission.

Summary of selected research projects:
Thermal instability in the intracluster/circumgalactic medium and its implications
Supernovae and their impact on the interstellar medium
Models of Fermi Bubbles in our Galactic center
Star clusters, winds, radiation and cosmic rays
Large and small scale magnetic fields in non-radiative accretion flows
Astrophysical radio background cannot explain the EDGES 21-cm signal: constraints from cooling of non-thermal electrons
Growth and structure of multiphase gas in the cloud-crushing problem with cooling
PhD students who want to join us are are welcome to talk to me and the students in the group.
Since we mostly do numerical simulations (although not always), some numerical experience will be desirable. Due to a large number of emails that I get, I may not be able to respond to all the emails.
