Particle Physics Theorist

Lawrence Hall

Professor Emeritus and Professor of the Graduate School

Lawrence Hall received his B.A. from Oxford in 1977 and his Ph.D. from Harvard in 1981. He was a Miller Fellow at Berkeley from 1981-83, and a junior faculty member at Harvard from 1983-86. He has been on the Berkeley faculty since 1986. He received Sloan and Presidential Young Investigator Awards, and is a Fellow of the American Physical Society.

Research Interests

What are the fundamental laws of nature, and how are they determined?

The standard model of particle physics, while very successful, leaves many fundamental questions unanswered. These questions frequently have to...

Raphael Bousso

Professor and The Chancellor's Chair in Physics

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...

Liang Dai

Visiting Assistant Professor

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.

If You Want to Go Far, Go Together: Professor Ben Safdi

Benjamin Safdi

Associate Professor Benjamin Safdi

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...

A highly magnetized neutron star

An artist's concept of a highly magnetized neutron star. According to current theory, axions would be created in the hot interior of the neutron star. UC Berkeley astrophysicists say that the strong magnetic field of the star will transform these axions into gamma rays that can be detected from Earth, pinpointing the mass of the axion.

We don't Make the Rules: Professor Geoffrey Penington

Geoff Penington

Assistant Professor Geoff Penington

The sketch of modern physics’ conundrum that we in the general public have a hazy picture of hasn’t changed for a hundred years. The cat is both kicking and has kicked, the electron is zipping around but we can’t know both where it is and how quick it is going, the particles are mysteriously linked in ways that appear faster than the speed of light,...
