Education Background

Ø Sept., 2006-Jun., 2013 a PhD student in College of Plan Protecting, Northwest A&F University. Research project is Pest Manage Ecological Engineering, and has been awarded the degree of Doctor of Science in Agriculture.

Ø 2000-2004  M.S. degree in applied mathematics, Applied Mathematics Department Northwest Agricultural and Forest (A&F) University, YangLing, China

Ø 1993-1997   B.S degree in basic mathematics, Mathematics Department of Northwest University, Xi’an, China.

Research Interests

Ø My research focuses on population dynamics and microorganism ferment using differential equation theory and statistics. I also studied bulk density of maize or wheat seeds using mathematical methods.

Ø Currently, I am working on mathematical modelling of predator-prey and other real question.

Employment Experience

Ø Nov.2008-Nov.2009, as a part of the biomathematical group in the school of Applied Mathematics, University of Western Ontario, London, Canada, my work is mainly to study predator-prey mathematical modelling of cotton aphid and ladybirds which is main natural enemy of cotton aphid through using Delay Differential Equation Theory.

Ø 1999-2022, working in Applied Mathematics Department, Northwest A&F University, China. Teaching subjects are Advanced Mathematics, Linear Algebra, Probability and Applied Mathematical Statistics. Research fields are mathematical model, data analysis and high education method.

Ø 1997-1999, working as an Assistant Lecturer in the Department of Applied Mathematics, Northwest Agricultural University, YangLing, China.
