Kiwi scientist and champion épée-fencer Dr Matt Baker is representing NZ at fencing in the final Olympic qualifying tournament in Dubai later today. Sydney-based Baker is Scientia Research Fellow in the School of Biotechnology and Biomolecular Sciences at the University of New South Wales, where he studies the molecular motor that makes bacteria swim. But today it's all about the sport and Matt is the sole NZ gladiator in men's épée. Age 41, and father of two young children, he's en garde against some up-coming young stars, all hungry for success at the Asia-Oceania Zonal Qualifier for the Paris Olympics. The men's épée starts at 4pm NZ time, streamed live.
