Biography

Dan Weisz received undergraduate degrees in physics and astronomy from UC Berkeley in 2004, followed by a PhD in astronomy and astrophysics from the University of Minnesota in 2010. He was a postdoctoral researcher for the Panchromatic Hubble Andromeda Treasury (PHAT) program at the University of Washington, serving as a Hubble Fellow. Dan joined the faculty of the Berkeley Astronomy Department in July 2016. During his time at Berkeley, he has led multiple large programs utilizing the Hubble Space Telescope (HST) and the James Webb Space Telescope (JWST) to survey the entire Andromeda Galaxy ecosystem and its satellite galaxy population. He is currently leading a stellar galaxy science mission known as the Ultraviolet Explorer (UVEX), which is a NASA-selected MIDEX-scale project set to launch in 2030. This mission aims to survey the entire sky in ultraviolet wavelengths and will potentially discover millions of low-mass galaxies as well as study the evolution of low-metallicity stars in the Large and Small Magellanic Clouds. Dan's broad research interests encompass low-mass galaxies, low-metallicity stars, and near-field cosmology. His contributions to the field have been recognized through multiple awards, including the Alfred P. Sloan Fellowship, the Alexander von Humboldt Fellowship, and the Newton Lacey Pierce Prize from the American Astronomical Society.
