As a fellow at MPIA in Heidelberg and with my graduate students Yu-Yen Chang and Michael Maseda I study the formation history of galaxies by tracing the population through cosmic time. The Hubble Space Telescope surveys listed here on the right combined with spectroscopic follow-up with ground-based facilities such as the Large Binocular Telescope and the Very Large Telescope provide the backbone of my projects.

HST surveys


The primary data product of this survey, led by Sandy Faber and Harry Ferguson, consists of HST/WFC3 imaging over 900 square arcminutes, divided over 5 different fields. The color mosaic shown above is the UDS.



Low-resolution grism spectroscopy for the same 5 fields to provide redshifts and emission line diagnostics.



Multi-band imaging of 25 galaxy clusters to constrain their dark matter distributions, and find supernovae and lensed background galaxies at high redshift.
