He has been a guest lecturer at the IOD, INSEAD and The Cranfield School of Management. He has published on the topics of leadership, relationship development and emotional resilience, and he speaks regularly at corporate events, conferences and workshops, to help motivate individuals and leaders to focus on ‘real impact’.

He worked with Dr Adrian Furnham, Professor of Psychology, to develop The GC Index®, an organometric and the first assessment instrument to identify Game Changers and the game-changing contributions individuals and teams can make. The GC Index® provides the framework and language that gives individuals clear focus for maximising their contribution.
