Research
I study how the large-scale environment affects galaxy evolution. I compare dwarf galaxies in voids with dwarf galaxies in more dense environments, in an effort to understand how a galaxy's environment affects its star formation history and chemical evolution. My work on the oxygen and nitrogen abundances in blue, star-forming dwarf galaxies in SDSS indicates that the void galaxies are retarded in their star formation and that they have larger dark-matter-halo-mass to stellar-mass ratios than dwarf galaxies in more dense environments.
