Research Interests: I am using spectroscopic and photometric data in the optical, near-infrared, and sub-mm to study early galaxy evolution (from z > 3 quiescent galaxies to the Epoch of Reionization). I am the U.S. lead principal investigator of ALPINE, a large, international ALMA program to study the dust and gas properties of z = 4-6 galaxies. I am also part of the scientific steering committee of the COSMOS collaboration and I am heavily involved in other projects such as our new COSMOS-Web JWST cycle 1 program. I am part of the SPHEREx science and pipeline team, the IPAC science platform, and the IPAC-led Joint Survey Processing initiative. I am also co-lead of the AGN group for CASTOR, a new Canada-led UV space telescope and the U.S. Euclid consortium.
