He was appointed assistant professor of physics at the University of Illinois, Urbana from 1968 to 1970. From 1970 to 1975 he was a fellow of the Center for Advanced Studies and an associate professor at the University of Virginia, Charlottesville. He was appointed professor of physics at University of Virginia from 1975 to 1988.

He obtained his Bachelor of Science at the University of Illinois in 1960, and later that year matriculated at Merton College, Oxford, where he took a second class degree in Physics in 1962. He read his Master of Arts at Oxford University (England) in 1962 where he studied as a Marshall Scholar. While at Oxford, Trefil was a member of the Oxford University men's basketball team. In 1964 he obtained his Master of Science at Stanford University and in 1966 his PhD (Physics) at Stanford University. His areas of research have included particle physics, fluid mechanics, medical physics and the earth sciences.

James Stanley Trefil (born September 10, 1938) is an American physicist (Ph.D. in Physics at Stanford University in 1966) and author of nearly fifty books. Much of his published work focuses on science for the general audience. He has served as Professor of Physics at the University of Virginia and, since 1988, as Robinson Professor of Physics at George Mason University. Among his books is Are We Unique?, an argument for human uniqueness in which he questions the comparisons between human intelligence and artificial intelligence. Trefil has also given presentations to judges and public officials about the intersections between science and the law.

Trefil was born on 10 September 1938 in Chicago, Illinois. He was the son of Stanley James Trefil (a personnel manager) and Sylvia (Mestek) Trefil (a social worker).
