个人简介
I am an observational cosmologist working in the fields of reionization, galaxy evolution, cluster cosmology and cosmic backgrounds. My group is active in science with Planck, Euclid, Herschel and the Spitzer Space Telescope in addition to a range of ground-based astronomical observation facilities such as Palomar, Keck, CSO, CARMA and ALMA. We are also involved in developing the next generation of small explorer missions in collaboration with JPL.
Specifically, we are measuring the properties of star-forming galaxies out to the highest redshifts, and in conjunction with studies of gamma-ray burst number densities and Type Ia supernovae, attempting to understand fundamental properties of galaxies, such as how they grow their stellar mass and metallicity, what is the stellar mass function therein, when does dust begin to play a significant role in their energetics and what fuels the star-formation as a function of cosmic time. We are using these measurements to provide, among other things, better constraints on the reionization history of the Universe between redshifts of 6 and 20 (the first billion years of time), which is arguably the most important astrophysical event since the Big Bang.
