My research focuses on the physics of gas in dark matter halos, known as the circumgalactic medium (CGM), and how it interacts with the galaxy at the center of the halo. The CGM constitutes the immediate environment of the galaxy, so physical processes in the CGM have a paramount effect on galaxy formation and evolution.

I use a wide range of tools in my work, including analytic derivations from first principles, hydrodynamic simulations including both idealized setups and fully-cosmological calculations, and inference from observations.

I also study the surroundings of massive black holes in the center of galaxies (with masses of millions to billions times the Sun mass), and how the physical process in these regions affect galaxy evolution, a process known as 'quasar feedback'.
