I have completed my PhD study in 2014 at McMaster University in Canada. My thesis focuses on asymptotic behaviour of three infinite dimensional diffusions arising from population genetics. After graduation, I worked at Zhongnan University of Economics and Law, and join Xi'an Jiaotong Liverpool University since September 2017. My research interests are mainly about asymptotic behaviours of Markov process, such as large deviation principle and moderate deviation principle in statistical physics and population genetics. Concentration inequality and some other type of non-asymptotic approximation would be my new interest due to its fundamental role in machine learning and random algorithm.
