Did Professor Shi Yigong Step Over the Line?

Professor Shi Yigong, who recently gave up a prestige position at Princeton to return to Tsinghua University, had been making a name for himself in China. Unlike the fellow returnee Professor Rao Yi, Shi Yigong tended to boast a higher personal profile. In an interview on Science Times, he claimed that his return was motivated by a strong patriotic brief. He expressed the desire to teach a new course on patriotism in Tsinghua.

Yet Professor Shi Yigong had already become an American citizen while he was in the United States. It might be quite awkward for him to teach such a course in China.

What's more, his status in Princeton was far from clear. It did not appear that he had simply given up his post as he had claimed. The Princeton University web site listed him simply as "on leave until September 2009", which means that he still maintains a position there.

There was no question that Professor Shi is working full time at Tshinghua right now. But his status at Princeton University brought up a questionable issue in his receiving a research grant from the Chinese National Natural Sceince Foundation. The grant, intended for outstanding young researchers, had a clear requirement for any applicant of non-Chinese citizenship that they should not be holding any position in a foreign institute at the time of their grant application. Professor Shi had clearly violated this rule.

Fang Zhouzi openly raised the issue to the Chinese National Natural Science Foundation, accusing Professor Shi Yigong's alleged forgery in his application. As usual, this ignited a vast controversy. Rao Yi defended his friend, claiming that it usually takes a long time for a professor to make a transition between institutions. But he could not address the issue of the grant directly. Shi Yigong chose to remain silent in public. In private, he offered to talk to Fang Zhouzi with an explanation. Fang Zhouzi declined, insisting on dicussing the issue in public.
