Prof.
Alex Pines, Ph.D., is the Glenn T. Seaborg Professor of Chemistry at the University of California at Berkeley and Faculty Senior Scientist at the Lawrence Berkeley National Laboratory.
Prof. Pines' research has focused on theory
and experimentation in nuclear magnetic resonance (NMR). Together
with John S. Waugh, he introduced high resolution NMR of dilute
spins such as carbon-13 and nitrogen-15 in solids, using cross
polarization (proton-enhanced nuclear induction spectroscopy).
He has pioneered the area of multiple-quantum spectroscopy
in which extended groups of spins flip coherently while absorbing
or emitting many quanta. His techniques of zero-field NMR
using both magnetic field cycling and superconducting (SQUID)
detectors are being applied to the study of molecular structure
and dynamics in condensed phases. His development of double
rotation and dynamic-angle spinning, involving the rotation
of a sample about two spatial axes according to the symmetry
of the icosahedron, extended high-resolution NMR to quadrupolar
nuclei such as oxygen-17 and aluminum-27 in solids. Other
recent interests include: iterative maps and chaos, quantum
(Berry) phase, topology, and gauge kinematics, drawing on
the analogy between the evolution of quantum spin systems
and the reorientation of cats falling from trees. His combination
of optical pumping and cross-polarization have made it possible
to observe enhanced NMR of surfaces and, most recently, the
selective "lighting up" of solution NMR and magnetic
resonance imaging (MRI) by means of laser-polarized xenon. His research
has had, and continues to have, impact from nanometers to meters and from
materials to biomedicine.
In 1991, Prof. Pines was awarded the Wolf
Prize in Chemistry. His other awards include: the ACS Baekland
Award in Pure Chemistry, the ACS Nobel Signature Award for
Graduate Education, the ACS Harrison Howe Award of the Rochester
Section, the DOE Ernest O. Lawrence Award, the Pittsburgh
Spectroscopy Award, the Bourke Medal of the Royal Society
of Chemistry, the ACS Langmuir Award, the Distinguished Teaching
Award of the University of California, and the Robert Foster
Cherry Great Teacher Award of Baylor University. Two of his
patents have been recognized by R&D-100 Awards. Prof.
Pines is a member of the National Academy of Sciences, a Foreign Member
of the Royal Society (London), and
past President of the International Society of Magnetic Resonance.
Among his many Lectureships, Prof. Pines has
been Joliot-Curie Professor at the Ecole Supérieure
de Physique et Chimie in Paris, Hinshelwood Lecturer at Oxford
University, Centenary Lecturer of the Royal Society of Chemistry
and Loeb Lecturer in Physics at Harvard University. He has received honorary
doctorates from the University of Paris and the University of Rome. After
completing his undergraduate studies in mathematics and chemistry
in Israel in 1967, he came to the United States in 1968, obtained
his Ph.D. in Chemical Physics and the Research Laboratory of Electronics at M.I.T. and joined the Berkeley
faculty in 1972.
