How Marc is building a better world

"I focus on how people live their lives and what that means for the future. A better understanding of how people think, feel and behave means better decisions can be made. I look to bring insight and inspiration to leaders so that the potential of their organization can be realised. 

Alongside all of the commercial work, I’m particularly proud of the impact of our research in helping to create strategies that change behavior for the better in areas like road safety. It has a profound impact on the lives of people."
