UCL Subsidiary Supervisor

I am an associate professor in financial mathematics at UCL and a Turing fellow at Alan Turing Institute since September 2016. Prior to this I was a visiting postdoctoral researcher at ICERM and Department of Applied Mathematics at Brown University from 2012/09 to 2013/05 and continued my postdoctoral research at the Oxford-Man Institute of Quantitative Finance until 2016. I finished my  D.Phil. in mathematics in 2012 under the supervision of Professor Terry Lyons at University of Oxford.

Research Themes
Research Summary

My research interests include stochastic analysis, financial mathematics and machine learning. More specifically I am interested in non-parametric modelling effects of data streams through rough paths theory and statistical models. Rough paths theory is a non-linear extension of classical theory of control differential equations to model highly oscillatory systems, and the core concept in rough paths theory is the signature of a path, which can be used as useful features for learning to summarize sequential data in terms of its effect. Moreover, I am also interested in its applications, e.g. online Chinese handwritten character recognition and financial data analysis.
