Generally my research interests focus on dwarf galaxy evolution.
More specifically, I am interested in how the environment surrounding a massive
galaxy modifies the properties of the satellite galaxies orbiting
within the hosts sphere of influence, roughly out to 1 Rvir.
Much of my time has been spent leading the design, data reduction, and
analysis of a Keck/DEIMOS survey of low-mass galaxies in the vicinity of
galaxy groups at intermediate redshift (z~0.8).
This study aims to pull together a spectroscopically complete catalog of
satellite galaxies down to log(Mstar) ~ 9.5 Msun around approximately 20
groups in the EGS and COSMOS extragalactic fields.
All of my published work to date has been systematically studying the properties
of the satellite galaxies in the Local Group. Ultimately putting together
a coherent model for environmental quenching around Milky Way-like hosts out
to ~2 Rvir, assuming the distribution of satellite galaxies around the Milky
Way and M31 are a respresentative sample.
This has led to a reasonably complete picture of environmental quenching extending down
to the stellar mass scale of the "classical" MW dwarf galaxies. The figure below nicely
presents an overview of this environmental quenching picture. For a more detailed description
of my work and the various implications please see my published work below.
