Welcome to my homepage. I'm an astronomer working in the Mikulski Archive for Space Telescopes (MAST) at the Space Telescope Science Institute (STScI). I study stars and exoplanets in the ultraviolet, optical, and infrared. I like to use space telescopes, large surveys, and archival data to conduct my research. I also like programming and am a big proponent of open source software in astronomy. Check out my research projects involving the missions below, or browse using the top navigation menu.
