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.
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
