Gerald Gabrielse is an American physicist and the George Vasmer Leverett Professor of Physics at
Harvard University . In 2007, he was elected a member of the National Academy of Sciences.Education
Gerald Gabrielse studied at
Trinity Christian College ,Illinois for two years and then moved toCalvin College ,Michigan . He graduated with a B.S. (honors) from Calvin College. He then completed his M.S. (1975) and Ph.D. (1980) in physics from theUniversity of Chicago .Academic career
After completing his PhD, he joined the faculty at the
University of Washington inSeattle . He became a professor of physics atHarvard University in 1987. He was named the George Vasmer Leverett Professor of Physics at Harvard University in 2003.Research
Gabrielse led the international TRAP team that developed the techniques to accumulate antiprotons at 4 K - an energy more than 1010 times lower than previously realized. These techniques are being used in all efforts to produce and study cold antihydrogen. These techniques also led to the most stringent CPT test with baryons when the charge-to-mass ratio of a single antiproton and proton were compared to 9 parts in 1011, an accuracy improved by nearly a factor of a million.
Gabrielse also led The international
ATRAP Collaboration which now uses these antiprotons to produce cold antihydrogen atoms, an important step towards comparing antihydrogen and hydrogen atoms via precise laser spectroscopy. The group's nestedPenning trap , invented and demonstrated at Harvard University as a method for getting cold antiprotons and cold positrons to interact, was the crucial device that first permitted the observation of cold antihydrogen. ATRAP's first demonstration of positron cooling in a nestedPenning trap established the crucial technique needed to first produce cold antihydrogen; ATRAP and others then used this device and method to observe cold antihydrogen. ATRAP's field ionization detection technique allowed a background-free observation and the first measurement of states of antihydrogen being produced, and their method to drive the production of antihydrogen substantially increased the production rate. ATRAP also demonstrated a second method to produce slow antihydrogen, for the first time using lasers to control the production via a charge exchange method.Religious views
Gabrielse identifies himself as a Reformed
Christian scientist. He said:I do not believe that science and the Bible are in conflict. However, it is possible to misunderstand the Bible and to misunderstand science. It is important to figure out what of each might be misunderstood.

On an episode of
Late Night with Conan O'Brien that aired on February 21, 2007, Jim Carrey and Conan O'Brien humorously discussed content from a paper entitled, "Stochastic Phase-Switching of a Parametrically-Driven Electron in a Penning Trap" [cite web |title=Stochastic Phase-Switching of a Parametrically-Driven Electron in a Penning Trap |url=http://hussle.harvard.edu/%7Egabrielse/gabrielse/papers/1999/DoubleWell.pdf |author=L.J. Lapidus, D. Enzer and G. Gabrielse |date=1999-08-02 |work=Physical Review Letters, vol. 83 no. 5, 899] Gerald Gabrielse said that it was 'perhaps the most obscure paper I've ever written'.
