Research

I dabble in Astrophysics, Cosmology, and Physics of gravity. I am obsessed with observational hints that could help address problems in fundamental physics. In particular, I have found anomalous signatures of dark energy and dark baryons in the cosmic microwave background radiation. With other collaborators, I have also developed a curious theory for an incompressible dark energy, named cuscuton (after the Latin name for the parasitic plant of dodder). I am currently trying my hand in solving the cosmological constant problem through a new theory of gravity that can surprisingly relate the formation of astrophysical black holes to today’s acceleration of cosmic expansion. In a related inquiry, I am also exploring the relation of cuscuton and quantum gravity.

My most exciting discoveries (so far) might be the Cosmological non-Constant problem, the most predictive theory of Big Bang, or Echoes from the Abyss!

Here are the broad areas of my research in Astrophysics, Cosmology, and Physics of Gravity. There is, of course, a lot of overlap between different areas, which can be seen by common papers listed under different fields.

• Quantum Field Theory in Curved Spacetime
• Black Hole Physics
• Early Universe Cosmology
• Cosmic Microwave Background
• Understanding Accretion Disks
• Cosmological Backreaction and the Role of non-linearities
• Missing Baryons of the Universe
• Understanding Dark Matter and Dark Energy
