Paul G. Huray, PhD, is Professor of Electrical Engineering at the University of South Carolina, where he has taught signal integrity, mathematical physics, and computer communications. Professor Huray introduced the first electromagnetics course to focus on signal integrity, and that program has produced more than eighty practicing signal integrity engineers now employed in academia, industry, and government. He earned his PhD in physics at the University of Tennessee in 1968, conducted research in the Solid State, Chemistry, and Physics Divisions at the Oak Ridge National Laboratory, and has worked part time for the Intel Corporation in developing the physical basis for barriers to circuits with bit rates up to 100 GHz.
