Daniel comes to UC Berkeley after spending 12 years as a professor at the University of Arizona. He completed his PhD at Caltech in 2008, then moved to the University of Cambridge as an STFC Research Fellow for 3 years. He spent 2 years as a Hubble Fellow at the University of Arizona before joining the faculty in 2013.
Daniel’s research focuses on the formation of the first generations of galaxies, stars, and black holes. He conducts observations of the high redshift universe using a variety of large telescopes and observatories (JWST, Keck, Magellan, ALMA). Using spectrographs on these facilities, he characterizes the nature of the most distant galaxies known, and the impact they have on the reionization of intergalactic hydrogen. He also studies nearby chemically primeval galaxies that are similar to those in the early universe using facilities across the electromagnetic spectrum.
Specialty areas: High redshift galaxies, spectroscopy, reionization, low mass and low metallicity galaxies, massive star populations in early galaxies.
