Philip H. Bucksbaum (b. January 14, 1953 in Grinnell, Iowa) is an American atomic physicist, who is the Marguerite Blake Wilbur Professor in Natural Science in the Departments of Physics, Applied Physics, and Photon Science at Stanford University and the SLAC National Accelerator Laboratory. He also directs the Stanford PULSE Institute. He develops and uses novel ultrafast strong field lasers to study fundamental interactions in atoms and molecules. His speciality is coherent control of the quantum dynamics of electrons, atoms, and molecules using coherent radiation pulses from the far-infrared to hard x-rays, with pulse durations from picoseconds to less than a femtosecond.

Early life and education
Bucksbaum spent his early childhood in Grinnell, a small farming and college community in south-central Iowa. He graduated as the class valedictorian from Washington High School in Cedar Rapids in 1971. He received a bachelor's degree in Physics from Harvard College in 1975.

Bucksbaum attended graduate school at the University of California at Berkeley, receiving his Ph.D. in 1980. His graduate research advisor was Eugene Commins.

Professional career
Following graduation and a one-year postdoctoral appointment at Lawrence Berkeley Laboratory, Bucksbaum joined Bell Telephone Laboratories in Holmdel, NJ as a postdoc. The following year he was promoted to a permanent member of technical staff at the Bell Labs Murray Hill location. He remained at Bell Labs through the 1980's. Columbia University appointed him Adjunct Associate Professor in Applied Physics in 1989. In 1990 he moved to Ann Arbor, MI to accept a Professorship in Physics at the University of Michigan. He became Otto Laporte Collegiate Professor in Physics in 1997, and Peter Franken University Professor in 2005.

Bucksbaum joined the faculty of Stanford in 2006, with joint appointments in Physics, Applied Physics, and Photon Science. He was named to the Marguerite Blake Wilbur Chair in Natural Science at Stanford in 2009, and currently directs the PULSE Institute at Stanford and SLAC.

Research summary
While at Harvard Bucksbaum was a research assistant in the groups of Robert Pound and Francis Pipkin. The subject of Bucksbaum's graduate research at Berkeley was the parity non-conserving neutral weak interaction in atomic thallium. He co-authored a textbook on the larger subject of electroweak interactions after completing his doctoral thesis.

At Bell Laboratories he became interested in ultrafast and strong field laser-matter interactions. For a time he co-held the record for the shortest wavelength coherent radiation ever produced in the laboratory. He also studied problems in solid state physics involving ultrafast short wavelength laser sources. 1n 1985 he turned to the study of strong-field ionization of atoms. His early work on above-threshold ionization of atoms established the role of ponderomotive forces in laser-electron interactions through studies of electron surfing in ultrafast laser pulses, the high-intensity Kapitza Dirac Effect , and the first observations of sub-picosecond strong-field ionization. He discovered and first explained the mechanism of bond-softening in strong-field molecular dissociation. His pioneering development of broadband coherent THz radiation (so-called “half-cycle pulses”) led to his fundamental studies of impulsive ionization of Rydberg atoms, which helped to advance the field of ultrafast THz spectroscopy. He has gone on to contributions using ultrafast lasers to study problems in quantum information, coherent control of atomic and molecular dynamics, and most recently strong-field coherent x-ray-atom physics at x-ray free electron lasers.

Professional Service
Bucksbaum has served on numerous committees and boards in physics. He has served terms on the American Physical Society Executive Board, the Optical Society Board of Directors, and the National Academy Board on Physics and Astronomy, as well as its Committee on AMO Science (CAMOS). He chaired the National Academy Decal Study in AMO Science, AMO 2010. He has also been a member of advisory committees for the Department of Energy Division on Basic Energy Science (BESAC), NIST (Committee for Physics), The National Science Foundation, and Science Advisory Committees for the Advanced Light Source at Berkeley National Lab, the Advanced Photon Source at Argonne National Lab, and the Linac Coherent Light Source at SLAC National Accelerator Lab, as well as numerous science centers and institutes. Currently (2013) he is Chair of the Board on Physics and Astronomy of the National Academy. He will assume the Presidency of the Optical Society in 2014.

At Stanford and SLAC, Bucksbaum has served as Chair of the Photon Science faculty and also Director of the Chemical Science Division. He has developed and taught courses at the undergraduate and graduate level.
