Last year GE’s CEO Jeff Immelt tapped Duan to oversee the industrial conglomerate’s portfolio of fast-growing China operations, with over 30 wholly-owned or joint venture companies ranging from aircraft engines to energy infrastructure. The dynamic 20-year group veteran, who started her career at the company, also continues to head the group’s health-care division in China, where she is repositioning the business to deliver customized offerings to an aging population (think next-gen imaging and portable diagnostic tools)—a critical growth driver for GE. —Rupali Arora
