In July 2010, UNAIDS (Joint United Nations Programme on HIV/AIDS) appointed him to a 17-member "High Level Commission" of renowned politicians, business leaders, human rights activists, and scientists tasked with spearheading a "social and political action campaign over the coming year aimed at galvanizing support for effective HIV prevention programmes."
同年7月，他被联合国艾滋病规划署选入一个由知名政治家、商业领袖、人权活动家和科学家组成的17人的“高级别委员会”，任务是“在来年发起一场社会和政治运动，旨在赢得大家对艾滋病预防计划的支持”。
