Dr. Harley grew up in South Africa where he attended the University of Pretoria and completed the BScEng and MScEng degrees in 1960 and 1965 respectively. He worked for the South African Railways and the University of Pretoria for a period of time, and then continued his graduate studies at Imperial College in London where he was awarded a PhD from the University of London in 1969.

He was appointed to the Chair of Electrical Machines and Power Systems at the University of Natal in Durban, South Africa, in 1971. In 1983 he became the Head of the Department of Electrical Engineering and in 1995 the Deputy Dean of Engineering at the University of Natal. He was a visiting professor to Iowa State University, to Clemson University and to Georgia Institute of Technology in 1975, 1985 and 1994 respectively. He came to Georgia Tech in February 1999 as the Duke Power Company Distinguished Professor. Dr. Harley was appointed as a Regents' Professor by Georgia Tech President G.P. "Bud" Peterson in August 2009.

He has published more than 220 papers in his field, is the co-author of a historical text book on Electrical Machines, supervised the research of 78 graduate students, and has received numerous awards and distinctions from professional societies. His hobbies include the guitar and woodworking.
