With its sterling reputation and its scientific bent, Shanghai Jiaotong University has the feel of an Ivy League institution.
The university has alliances with elite American ones like Duke and the University of Michigan. And it is so rich in science and engineering talent that Microsoft and Intel have moved into a research park adjacent to the school.

But analysts say Jiaotong and Lanxiang are certain to come under close scrutiny.
Jiaotong is one of the top universities in China and one charged with helping transform this country into a science and technology powerhouse.
The school has exchange programs with some of the world’s leading universities. Earlier this year, Duke University in North Carolina said that with the help of Jiaotong, it…
