I was the Principal Investigator for the Extended Baryon Oscillation Spectroscopic Survey to constrain cosmology through the clustering of matter on scales of hundreds of millions of lightyears. In July, 2020, we released our final measurements and cosmological interpretation. A summary of this program can be found in the international press release and accompanying video.

I am now the co-Spokesperson for the Dark Energy Spectroscopic Instrument (DESI). DESI will be the largest spectroscopic survey ever conducted, designed to map the cosmic distance scale and growth of structure over the last 12 billion years.
