Overview of RESEARCH and TEACHING

Resume (pdf) and Publications (pdf)

About Me I am an astronomer at the Space Telescope Science Institute (STScI) in Baltimore, Maryland, where I am a member of the Science Mission Office (SMO) and the Science Policy Group. My research focuses on galaxy formation and evolution, particularly on the role played by diffuse gas in and around galaxies. Much of my work uses ultraviolet and optical spectroscopy to observe these gas reservoirs in absorption. Click here for more details. Before joining STScI, I worked at the Institute of Astronomy (IoA) in Cambridge, England, the European Southern Observatory (ESO) in Chile, the Institut d'Astrophysique de Paris (IAP), the University of Wisconsin-Madison (UW-Madison), and University College London (UCL).

May 2013: See this recent Nature news article on our Magellanic Stream results.

Research Interests - Interstellar, circumgalactic, and intergalactic media
- High-velocity clouds (HVCs): abundances, ionized phases, origin and fate
- Damped Lyman-alpha systems (DLAs): abundances, kinematics, hot gas content
- Gaseous inflow and outflow: observational tracers, effects on galaxy evolution
- Gamma-ray burst host galaxies: ISM properties, ionization modeling
