Zhan Tao (Chinese: 展涛; born April 1963) is a Chinese mathematician who served as president of Jilin University from 2008 to 2011 and president of Shandong University from 2000 to 2008.
He is now a standing member of the Chinese Association of Mathematics, deputy director of the Young Scientist Association of China, a standing member of the All China Youth Federation, vice president of the Shandong Youth Federation, and board chairman of the Shandong Association of Mathematics.
Since joining the faculty of Shandong University in 1987, he has been working on classical problems in number theory such as estimates of exponential sums over primes, mean-value theorems for arithmetic progressions, and Goldbach's conjecture.
In particular, he has solved the quadratic almost Goldbach conjecture, and has successfully proved a new form of the Three-Prime theorem in arithmetic progressions to large moduli.
Zhan also participated in a co-research program at the Albert Ludwigs University of Freiburg in Germany from January, 1991 through December, 1992, and he has been invited by dozens of universities in France, the Netherlands and United States for short academic visits.
