Rodney L. Lowman, PhD (born 1949) is an American psychologist, academic administrator and entrepreneur whose major contributions have been in the areas of career assessment and counseling, ethical issues in Industrial and Organizational Psychology (I-O Psychology), the integration of clinical psychology and I-O psychology and helping to develop the field of Consulting Psychology. In a study of the most prolific contributors to the Consulting Psychology Journal: Practice and Research, Lowman was rated the second highest contributor for articles for the period 1992-2007.
Lowman's training in both Industrial-Organizational (I-O) and clinical psychology resulted in an interest in ethics. The field of Industrial and organizational psychology (Society of Industrial-Organizational Psychology [SIOP]) though being closely tied to both science and practice had not focused much on ethics in the practice of I-O psychology. As chair of SIOP's Professional Affairs Committee, Lowman led the effort to create SIOP's first ethics casebook, which has since been expanded and published in two editions in a joint publication by APA and SIOP, The Ethical Practice of Psychology in Organizations. Lowman (both independently and with colleagues such as Drs. Richard Kilburg and Stewart Cooper) have conducted a large number of professional training programs for psychologists on the application of ethics in consulting and I-O psychology.
The field of consulting psychology has also been a focus of Lowman's professional work. He spearheaded and helped obtain the APA's approval for a set of guidelines for the training of professional consulting psychologists at the doctoral and post-doctoral levels. In these training models the focus is on training at the individual, group and organizational levels. He edited a book that helped to advance Consulting Psychology as a discipline, the Handbook of Organizational Consulting Psychology. In 2011, he was the keynote presenter at the Responsible and Ethical Leadership conference, University of Johannesburg, South Africa and at the Consulting Psychology in Africa: Breaking New Ground conference sponsored by the University of South Africa in Pretoria.
