Jihyun Cho Sparrow joined Willis Towers Watson in Hong Kong as a director of its investment business, which includes the firm's strategic advisory and outsourced CIO businesses.
The position is a new one, reflecting growing demand from institutional investors in the region for advice in managing their portfolios, a spokeswoman said.
Ms. Sparrow will report to Jayne Bok, the firm's head of investments for Asia.
She comes to Willis Towers Watson from American Century Investments in Hong Kong where she served as a vice president in the firm's global client group.
An American Century spokesman said a replacement for that role has been selected but offered no further details.
