Dr Yubin Yan

Postgraduate Programme Leader

Yubin graduated from  Shanxi Normal University,  P.R. China in 1985 with a BSc in Mathematics. He went on to obtain his MSc in Mathematics in 1991 from  Harbin institute of Technology, P. R. China and completed his PhD in Mathematics in 2003 from Chalmers University of Technology, Sweden.




Yubin joined the University of Chester in September 2007 as a lecturer in Mathematics. After one year, he was promoted to a senior lecturer position in the Maths Department.

Before he joined Chester in 2007, he was a research associate in the Department of Automatic Control and System Engineering at the University of Sheffield (from 2004 to 2007), and a research associate in the Department of Mathematics at the University of Manchester (from 2003 to 2004).

Yubin enjoys teaching Mathematics very much. He also enjoys learning Mathematics and working with people.
