Gerald Gabrielse is an American physicist and the George Vasmer Leverett Professor of Physics at Harvard University. He is primarily known for his experiments trapping and investigating antimatter, measuring the electron g-factor, and measuring the electron electric dipole moment. He has been described as "a leader in super-precise measurements of fundamental particles and the study of anti-matter."
Gabrielse attended Trinity Christian College and then Calvin College, graduating with a B.S. (honors) in 1973. He then completed his M.S. (1975) and Ph.D. (1980) in physics from the University of Chicago under Henry Gordon Berry. Gabrielse became a postdoc at the University of Washington in Seattle in 1978 under Hans Dehmelt, and joined the faculty in 1985. He became Professor of Physics at Harvard University in 1987, and the chair of the Harvard Physics Department in 2000. He is currently the George Vasmer Leverett Professor of Physics at Harvard.
In November 2015, it was announced that the Gabrielse group would be moving to Northwestern University in 2017 as part of the newly created Center for Fundamental Physics at Low Energy. Gabrielse will the first Director of the center.
Gabrielse was a pioneer in the field of low energy antiproton and antihydrogen physics by proposing the trapping of antiprotons from a storage ring, cooling them in collisions with trapped electrons, and the use of these to form low energy antihydrogen atoms. He led the TRAP team that realized the first antiproton trapping, the first electron cooling of trapped antiprotons, and the accumulation of antiprotons in a 4 Kelvin apparatus. The demonstrations and methods made possible an effort that grew to involve 4 international collaborations of physicists working at CERN's Antiproton Decelerator. In 1999, Gabrielse's TRAP team made the most precise test of the Standard Model's fundamental CPT theorem by comparing the charge-to-mass ratio of a single trapped antiproton with that of a proton to a precision of 9 parts in 1011. The precision of the resulting confirmation of the Standard Model prediction exceeded that of earlier comparisons by nearly a factor of 106.
