Stochastic analysis, financial mathematics and data analysis: Currently I work as a postdoctoral fellow within ERC project of Prof. Terry Lyons. My research interest is to model the evolution of complex systems that are affected by noise using the theory of rough path and its applications.
Oct 2014 - Nov 2014: Lecturer for the introduction of Rough Path Theory, University of Oxford.
Oct 2014 -Dec 2014: Tutor for MSc course - Statistics and Financial Data Analysis, University of Oxford.
Jan 2013 -May 2013: Teaching Assistant for the APMA1200 course Operations Research: Probabilistic Models, Brown University.
