Hitoshi Murayama

Professor, Former Director, Kavli Institute for the Physics and Mathematics of the Universe (IPMU), University of Tokyo

Hitoshi Murayama is a well-known theoretical particle physicist who works broadly, even on astrophysics, cosmology, and condensed matter physics. He has been a professor in the University of California, Berkeley, since 2000, and is also the founding director of the Kavli Institute for the Physics and Mathematics of the Universe (Kavli IPMU) at the University of Tokyo, serving from 2007 to 2018. Born in Japan, lived in Germany for four years and in the US for 21 years, served on advisory committees around the world, he is a multicultural global denizen. In October 2014, he was invited to...

Petr Horava


Petr Horava received his Ph.D. in 1991 at the Institute of Physics of the Czech Academy of Sciences in Prague. He was awarded the Robert McCormick Research Fellowship at the Enrico Fermi Institute at the University of Chicago, worked as a Research Associate at Princeton University, and won a Sherman Fairchild Senior Research Fellowship at Caltech, before joining the New High Energy Theory Center at Rutgers University in 2000 as an Associate Professor. In 1997, he was awarded the Junior Prize of the Czech Learned Society, and in 1999 he appeared on the list of top three scientists of the...

Lawrence Hall


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...

Ori Ganor

Associate Professor

Ori Ganor received his B.Sc. in 1988 and his Ph.D. in 1996, both from Tel-Aviv University. He was a Robert H. Dicke fellow from 1996 until 1998 and an assistant professor from 1998 until 2001 at Princeton University. He joined the UC Berkeley Physics faculty as an associate professor in 2002.

Research Interests

My general field of research is String Theory, which is an umbrella term for a worldwide effort in theoretical high-energy physics, ranging from a quest for the fundamental Laws of Nature, looking at gravity under extreme conditions, applications and new models for particle...

Mary K. Gaillard

Professor Emeritus

Ph.D., University of Paris, 1968, Professor at Berkeley since 1981. Member, National Academy of Sciences, Fellow, American Academy of Arts and Sciences, l988 E.O. Lawrence Memorial Award, 1993 J.J. Sakurai Prize, Member, National Science Board, Member 1996-2002, American Philosophical Society.

Research Interests

I am interested in pushing particle theory beyond the well-established Standard Model. My work in recent years has focused on the symmetry breaking mechanism by which particles acquire masses, and more specifically on supersymmetry and supergravity. Supersymmetry provides a...

Liang Dai

Assistant Professor and The Michael M. Garland Chair in Physics

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.
