Recent work

Gas Accretion book

I recently edited a book on Gas Accretion onto Galaxies, published by Springer. This is a contributed volume with 15 chapters written by 15 authors reviewing the subject of how galaxies get the fuel they need to form stars. Find the chapters here.

Galactic Center Outflow

I'm the PI of a 49-orbit HST program to study the Galactic Center region in UV absorption. Our results reporting the discovery of the kinematic signature of a biconical outflow are described in two NASA press releases available here and here.

Magellanic Stream

The Magellanic Stream is a giant tidal tail of gas stipped out the Magellanic Clouds. See the Annual Reviews article I wrote with Elena D'Onghia on this fascinating object, or see this press release describing how we've explored its origin using chemical abundance analysis.

Bio

I'm an ESA/AURA astronomer at the Space Telescope Science Institute (STScI) in Baltimore, Maryland, the scientific home of the Hubble Space Telescope and the James Webb Space Telescope. My research focuses on diffuse gas in and around galaxies (particularly the Milky Way), and the role it plays in fueling star formation. My work uses ultraviolet, optical, and radio spectroscopy to determine the physical and chemical properties of the gas in galaxy halos. At STScI, I'm a member of the COS Instrument Team in the INS division, where I lead the User Support Block, and I also organize the review process for Director's Discretionary time on the Hubble telescope. Before joining STScI, I worked at the Institute of Astronomy (IoA) in Cambridge, UK, the European Southern Observatory (ESO) in Chile, the Institut d'Astrophysique de Paris (IAP), the University of Wisconsin-Madison, and University College London (UCL)
