Research Summary

I study the fundamental properties of the Universe through observational cosmology. I am the Principal Investigator for the extended Baryon Oscillation Spectroscopic Survey (eBOSS) at Apache Point Observatory. In eBOSS, we will place the most precise distance constraints to date in the 0.8<z<3.5 redshift range. I also help prepare the cosmology program for the Dark Energy Spectroscopic Instrument (DESI). DESI will begin in 2020 and will be 10X larger than any other spectroscopic program.
