Professor Gerald Gabrielse is the George Vasmer Leverett Professor of Physics at Harvard University. His research efforts include a variety of atomic, optical, elementary particle, plasma and low temperature physics experiments. He leads the international ATRAP Collaboration at CERN in Geneva, Switzerland whose goal is accurate laser spectroscopy with trapped antihydrogen atoms. His experiments have twice been selected as the physics story of the year by the American Institute of Physics – first when he produced cold antihydrogen atoms, and most recently when he used a single suspended electron to dramatically improve the accuracy with which we know the fundamental fine structure constant. He typically gives up to 50 outside lectures each year, at scientific conferences, university colloquia, popular science venues, and in high schools. Professor Gabrielse is a member of the US National Academy of Sciences. He has received the Davisson-Germer Prize of the American Physical Society, Germany’s Alexander von Humboldt Research Award and Italy’s Tomassoni Prize. He is the former chair of the Harvard physics department, and Harvard has awarded him both its Levenson Teaching Prize for outstanding teaching of undergraduate non-science students, and its Ledlie Prize for exceptional research accomplishment. Both Calvin College and Trinity College recognized him with a distinguished alumnus award. He served as scientist in residence for a local high school and taught physics there for one year. He gave the Rosenthal Lecture at Yale, the Faraday Lecture at Oxford, was the Zachariasen Lecture at the University of Chicago, the Kallen Lecturer in Sweden, and a Poincare Lecturer in France.
