About Diaan-Yi

Diaan-Yi is managing partner of our Singapore office and a leader in our Public Sector, Private Equity, and Capital Projects & Infrastructure Practices in Asia. She also helps direct our work with sovereign wealth funds in the region. A Malaysian citizen currently based in Singapore, she has worked extensively with government entities and government-linked companies in Asia, particularly on the design and implementation of large-scale programs to drive performance transformation and economic development. She also specializes in setting up efficient and effective public-private partnerships.

Diaan-Yi is an expert in building alignment among multiple government entities. Examples of her recent projects include advising an Asian government on detailed implementation plans to transform its pre-primary school system, supporting a public-sector institution on a major portfolio-management effort, and helping develop a public-private partnership to increase employability among students and graduates. In addition to her public-sector work, she has served clients in many industries—including financial services, telecommunications, logistics, energy, and retail—on a range of issues such as strategy, corporate governance, and corporate finance.

Before joining McKinsey in 2002, Diaan-Yi worked as an investment banker at Credit Suisse First Boston in New York and London. She was a core member of the equity private placements group, responsible for securing mandates, marketing transactions to potential investors, and structuring and pricing equity transactions for companies that required growth capital.
