He is a member of Singapore’s Future Economy Council, which is chaired by Singapore’s finance minister and comprises members from government, industry, union, and educational and training institutions. At McKinsey, he is a member of the MGI Council, which advises the think tank’s research on global economic, business, and technology trends.
