The Obscured Universe
From the First Galaxies to Today

My research focuses on galaxy formation and evolution, from the earliest times after the Big Bang to the present day.  I’m particularly interested in the most massive and luminous galaxies in the Universe, which form stars at rates several hundreds of times higher than our own Milky Way.  These extreme, starbursting galaxies pose a unique challenge to cosmological simulations and galaxy formation theory.  To date, they have been very difficult to study with optical telescopes because they are also extremely dusty and gas-rich, so learning more about their physical mechanisms requires observations at submillimeter to radio wavelengths, where cold gas and dust emit energy.

Extreme Galaxies

Though hundreds of times more rare than "Milky Way" type galaxies, the Universe's most massive, intense starbursts may be the key to unlocking the physics of star formation and the relationship between galaxies and their environment in large scale structure.

Our Research Group

I'm very lucky to work with a fantastic team of students and researchers at UT Austin. Meet each of us working to solve the mysteries of obscured galaxies, from resolved dynamics of nearby galaxies to molecular gas in the distant Universe, large radio surveys of galaxy cluster fields, and simulations for the next generation of facilities.
