My main research interests lie in galaxy halos and the evolution of galaxies.

With the extremely sensitive high resolution UV spectrograph (COS) onboard the Hubble Space Telescope coupled with ground-based observatories (LBT, Keck,...), I pursue some of the science frontier questions in modern astrophysics and cosmology:

How do baryons cycle in and out of galaxies?

What controls the mass-energy-chemical cycles in galaxies?
