George R. Blumenthal is UC Santa Cruz's 10th chancellor. He joined the campus in 1972 as a
professor of astronomy and astrophysics. He was named chancellor on September 19, 2007 after serving as acting chancellor for 14 months (July
14, 2006-September 18, 2007).
His appointment followed many years as a distinguished professor, researcher, and campus leader; he
held several key leadership roles in the University of California system, as well. During 2004-2005,
Blumenthal served as chair of the UC Academic Senate. He was faculty representative to the UC
Regents from 2003 to 2005, and he chaired the UC Santa Cruz division of the Academic Senate from
2001 to 2003. Earlier, he served as department chair of Astronomy and Astrophysics. In 2010,
Blumenthal received the Oliver Johnson Award for Distinguished Leadership in the Academic Senate,
the top UC honor for service at both the systemwide and campus levels.
Chancellor Blumenthal is well known for his efforts to increase access to the University and for his
commitment to diversity among students, staff, and faculty. In 2012, he received the Outstanding
Senior Leadership Award from the Council of University of California Staff Assemblies (CUCSA) in
recognition of his advocacy on behalf of staff; he has been an honorary member of CUCSA since 2005.
Chancellor Blumenthal serves widely on many governing boards in science, technology, and education.
In higher education, Chancellor Blumenthal is co-chairman of the Joint Graduate Board of the UC and
California State University systems. He is vice chairman of the California Association for Research
in Astronomy, which oversees the W. M. Keck Observatory on the summit of Mauna Kea, Hawaii, and he
is a member of the California Council on Science and Technology. He is also a member of the board of
directors of BASIC, the Bay Area Science and Technology Consortium.
In Silicon Valley, Chancellor Blumenthal is chairman of University Associates - Silicon Valley LLC
and a board member of Joint Venture Silicon Valley and the Silicon Valley Leadership Group; he is
also co-chair of SVLG's Higher Education Task Force.
As a theoretical astrophysicist, Chancellor Blumenthal made pathbreaking contributions to our
understanding of the origin of structure in the universe, including galaxies and clusters of
galaxies, and to the role that dark matter plays in the formation and evolution of this structure.
His expertise spans related cosmological issues, such as the generation of density fluctuations
during an early inflationary phase of the universe. He has studied gamma-ray bursts, accretion
disks, and active galactic nuclei. He is a co-author of the astronomy texts 21st Century Astronomy,
now in its fourth edition, and Understanding Our Universe, the second edition of which is
forthcoming in late 2014.
He earned his bachelor of science at the University of Wisconsin-Milwaukee and his Ph.D. in physics
at the University of California, San Diego. In 2011, he was awarded an honorary Ph.D. in
astrophysics and leadership in higher education from the University of Wisconsin-Milwaukee.
He is married to Kelly Weisberg, a professor of law at UC Hastings College of the Law in San
Francisco. They have two children.
