Dr. Nathan Isgur
Former Chief Scientist
Dr. Nathan Isgur, Jefferson Lab's former Chief Scientist, advised the Director on the planning and interpretation of the Jefferson Lab experimental program, served as a member of Jefferson Lab's Director's Council, and was head of the Lab's Bridge and Joint Professorship Program (the University Relations Office). Dr. Isgur received a B.S. in physics from California Institute of Technology (Caltech) and his Ph.D. in Physics from the University of Toronto. He served as a Professor of Physics at Toronto from 1974 until 1990 when he joined the faculty of the College of William and Mary and became the Theory Group Leader at Jefferson Lab.
Dr. Isgur was the recipient of the Steacie Prize, the Herzberg Medal, the Rutherford Medal, and the Sakurai Prize. He was a fellow of the Royal Society of Canada and of the American Physical Society. He published over 100 papers on the quark structure of matter and was perhaps best known for his work on the excited states of the proton and for his role in the discovery of a new symmetry of nature which describes the behavior of heavy quarks.
