Today, the Netherlands Centre for Doping Affairs and the World Anti-Doping Agency hosted a symposium about gene doping. the intention of this meeting was to develop collaboration with scientists, with a view to finding ways of understanding what might next be used by athletes. WADA Science Director Dr Oliver Rabin was attending and I certainly can't imagine a more helpful scientist to be leading the policy on this matter. He is open to recognising the limitations of WADA as a social institution and interested to develop a wide-ranging debate on the value of enhancement in sport.
