Greetings! 

I'm a Hubble Fellow at the Space Telescope Science Institute. 

I'm interested in how galaxies form and evolve, from the smallest dwarf galaxies to large galaxies like the Milky Way. I use the resolved stellar populations, interstellar content, and satellite populations of local galaxies roughly the size of our Milky Way to understand how they change over time, especially as a result of their interactions with other galaxies.
