I am a Research Associate in the Institute for Astrophysics at the Univserity of Minnesota. I received my MS in Astrophysics from Boston University in 2001 and completed my PhD at the University of Minnesota in 2010. Prior to astronomy, my work experience includes nearly a decade of consulting in business on projects ranging from the strategic integration of technology to envrionemntal regulatory compliance for major industry.

Research Interests

My research focuses on probing the different variables that play a role in galaxy evolution. Specifically, I study nearby galaxies where the detailed physics of star formation, stellar feedback processes, and gas dynamics can be studied in detail. One of my main projects over the past few years has been the STARBurst IRregular Dwarfs Survey (STARBIRDS) which interweaves information across the electromagnetic spectrum to understand the starburst mode of star formation in low-mass galaxies. The STARBIRDS data set includes imaging from the Chandra Space Telescope (X-ray), GALEX Telescope (ultraviolet), Hubble Space Telescope (optical), KPNO Telescopes (Halpha), Spitzer Space Telescope (infrared), and the Green Bank Telescope (21 cm). In addition, I have been studying a newly discovered galaxy, Leo P (see UMN press release link above) which is one of the least chemically enriched gas-rich galaxies every found.

I am also involved in a number of other galaxy surveys. DUST in Nearby Galaxies with Spitzer (DUSTINGS; PI Boyer) seeks to understand dust production from exolved stars in 50 Local Group dwarf galaxies. The Survey of HI in Extremely Low-mass Dwarfs (SHIELD; PI Cannon) aims to study star formation and evolution at the faint-end of the galaxy luminosity function. Finally, a deep optical survey of some of Andromeda dwarf galaxies (PI Skillman) is probing the properties of the first epoch of star formation in a population of satellite galaxies.
