When Yeo arrived at the Agency for Science, Technology and Research (A*STAR) in 2001, he found that fewer than 20% of PhD holders in A*STAR's institutes were Singaporean, and few among them were young scientists. Yeo immediately set up his boldest scholarship yet by setting up the A*STAR Graduate Academy to implement the plan to train up 1,000 PhD scholars that would eventually return to Singapore and undertake research in fields like information technology, engineering, molecular biology, biochemistry and medicine. One of the hallmarks of Yeo's personal style is the amount of personal attention he gives to his scholars. He takes great pains to remember personal details about their background and also closely tracks their academic performance. He regularly meets with them to buy them meals whenever he is near their overseas universities on his regular business trips abroad.
