My research interests broadly cover issues concerning the formation and evolution of galaxies across cosmic time. In particular, I am interested in the properties of diffuse gas in and around galaxies and quasars. My group’s expertise lies in galaxy surveys, integral field spectroscopy of extended nebulae, and absorption-line spectroscopy of distant light sources (quasars/gamma-ray burst afterglows). These approaches enable comprehensive studies of baryon cycles between star-forming regions and the intergalactic medium. For those interested in getting involved in astrophysics research on diffuse cosmic gas, please check out the Encyclopedia of Astrophysics chapter on the circumgalactic medium.
