If you have watched any of the shows on the History or Discovery Channel on the history of physics, you probably know that one of the latest trends in theoretical physics is string theory. In RIA terms, we might call string theory a mashup of quantum theory and general relativity. The mathematics involved in string theory are quite advanced and an important researcher in this field is Dr. Clifford Johnson.
Dr. Johnson was born in London and obtained his undergraduate degree from the Imperial College of London. He obtained his Ph.D. in Physics from Southampton University and did his post-doc work at the Princeton Institute for Advanced Study.
He is currently on the faculty of USC in the dept. of Physics and Astronomy. For more information on Dr. Johnson, check out this page which includes a list of publications.
