Benjamin Safdi received his undergraduate degree from the University of Colorado at Boulder, a Master of Advanced Study from Cambridge University, as a Churchill Scholar, and his PhD from Princeton University in 2014. He was then a Pappalardo Fellow in physics at the Massachusetts Institute of Technology until 2017, when he started as an assistant professor at the University of Michigan, Ann Arbor. Dr. Safdi moved to LBNL in 2020 and then to UC Berkeley in 2021. He received the Department of Energy Early Career Award in 2018, the IUPAP C11 Young Scientist Prize in Particles and Fields in...
Raphael Bousso received his Ph.D. from Cambridge University in 1998 and went on to become a Postdoc at Stanford University. He also worked at the Kavli Institute for Theoretical Physics in Santa Barbara. In 2002/03 he was a fellow at the Harvard University physics department and the Radcliffe Institute for Advanced Study. In July 2003 he joined the physics department at UC Berkeley.
Research Interests
My interests are in theoretical cosmology and quantum gravity.
The central principles of quantum mechanics and of general relativity (our classical theory of gravity) come into...
Prof. Dai received a B.S. in Physics from Peking University in 2011. Later on, he earned his Ph.D. in Physics from the Johns Hopkins University in 2015 working on theoretical cosmology. From 2015 to 2018, he was awarded an NASA Einstein fellowship and was appointed a postdoctoral Member at the Institute for Advanced Study in the School of Natural Sciences. From 2018 to 2020, he was a long-term John Bahcall postdoctoral fellow at the Institute for Advanced Study, before he joined the faculty in the Department of Physics at the University of California, Berkeley.

Artist’s conception of a magnetar surrounded by an accretion disk that is wobbling, or precessing, because of the effects of general relativity. Some models of magnetars suggest that high-speed jets of charged particles emanate from the magnetar along its rotation axis. Image: Joseph Farah and Curtis McCully/Las Cumbres Observatory
Studying the physics of atomic particles takes a lot of room. The Large Hadron Collider at CERN, the biggest particle accelerator, is in a ring tunnel 27km (17 miles) long buried about two football fields deep underground. It serves as the factory, or artisanal manufacturer, of bespoke subatomic particles like quarks. But where is the design studio for these...
The Pinwheel Galaxy, or Messier 101, on May 21, 2023, four days after the light from the supernova 2023ixf reached Earth.
Alex Filippenko is the kind of guy who brings a telescope to a party. True to form, at a soiree on May 18 this year, he wowed his hosts with images of star clusters and colorful galaxies — including the dramatic spiral Pinwheel Galaxy — and snapped...
