I am a cosmologist.

I have worked on understanding the nature of dark matter, weak and strong gravitational lensing, clusters of galaxies, secondary anisotropies of the cosmic microwave background (CMB) radiation, the clustering of high redshift quasars, the Lyα forest and quasar absorption line systems, the interface between quasars and the intergalactic medium (IGM), and on understanding the nature of high redshift galaxies.

My past research has been analytical, numerical, and observational and I’ve published work in both theoretical and observational astrophysics. I consider myself to be both a theorist and an observer and collaborate with members of both groups.
