As one of the co-founders of WatCACE, he has examined training for work, teamwork in the workplace, training development and evaluation. He has co-authored and co-edited nine books examining the various aspects of human performance. While not currently researching co-operative education, he remains interested in the research activities of the Work-Learn Institute and the development of co-operative education programs.
