孙永征，中国矿业大学 数学学院-k8凯发旗舰

i  received the  ph.d. degree from fudan university in 2010. from feb. 2014 to jan. 2015, i was an academic visitor at the university of oxford. from jan. 2016 to mar. 2016 i was an academic scholar at issac newton mathematics institute, university of cambridge. at present,  i am a full professor at school of mathematics, china university of mining and technology. currently (from january 2017),  i  am serving as the vice dean of school of  mathematics, and the vice director of the applied mathematics center of jiangsu province.  my research interests focus on the mathematical modeling of complex systems. in general, i have a deep interest in  complex networks, collective animal motion, stochastic dynamics, and chaos. the aim is to reveal the fundamental mechanism of noise in poorly understood complex systems.  some results have been published in several high-impact journals in physics, mathematics, and nonlinear science such as physical review letters, physical review research,physical review e, siam journal on applied mathematics,  chaos, ieee tac， ieee tsmc, ieee tnse.
