I am a Reader at the Department of Statistics. My past positions include Associate Professor in the University of Warwick, Lecturer in King’s College London and Postdoctoral Research Fellow at the Oxford-Man Institute of Quantitative Finance. In 2018-2019, I was awarded FRIAS Senior Fellow and Marie Curie Fellow at the Freiburg Institute of Advanced Studies (FRIAS), University of Freiburg. I completed my D.Phil. (Ph.D.) in Mathematics at the Mathematical Institute, Oxford University in 2011, under the supervision of Terry Lyons and Zhongmin Qian.
My research interests are mainly focused on mathematical finance and stochastic control. I am especially interested in
- stochastic control and backward stochastic differential equations;
- optimal stopping and free boundary problems;
- viscosity solutions and numerics;
- optimal investment and forward preferences;
- credit and funding liquidity risks.
