Professor Currie's contribution to the field of Public Transport is unsurpassed. This stems from his core belief that an academic in his position has a responsibility to do more than just publish research papers: they need to teach the community and drive real-world change. For decades Graham has embodied these principles, giving invited presentations almost every other week, chairing a research committee in the world's largest body associated with the field, and globally advising governments and the private sector alike on how to effectively develop and apply technologies, old and new, in the public transport industry.
