I am an Astronomer, and a Physicist; in short I am an astrophysicist. I am an Assistant Professor in the Astrophysics and Gravitation group at the Department of Physics and Astronomy University of Waterloo. I am also an Associate Faculty in the Cosmology group at the Perimeter Institute for Theoretical Physic (PI). 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.
