Stephanie Ho works on topics related to galaxy evolution, focusing on the diffuse gas around galaxies known as the circumgalactic medium (CGM). In particular, Stephanie is interested in the interplay between galaxies and the CGM -- how the CGM feeds the galactic disks and grows the disks inside-out, and how galactic outflows affect the CGM and regulate the star formation of galaxies.
Stephanie studies the CGM using both observations and simulations. She uses the Hubble Space Telescope and ground-based telescopes (UV, optical, and near-IR) to conduct quasar absorption-line studies, galaxy spectroscopy, and imaging. She also analyzes cosmological simulations to study the circumgalactic gas kinematics and gas accretion from a theoretical perspective.
Prior to arriving at Texas A&M, Stephanie obtained her PhD (Physics) at the University of California, Santa Barbara, where she worked with Prof. Crystal Martin to study the kinematics of the cool circumgalactic gas (thesis: How Do Galaxies Get Their Gas?).
