I am a Lecturer in Mathematical Finance and Statistics in the Department of Mathematics at Imperial College London. Before joining Imperial, I was a Postdoctoral Research Fellow with CREATES at Aarhus University, Denmark. I maintain ties with CREATES as an International Fellow. I received my PhD in Applied Mathematics and MSc in Mathematics from the University of Helsinki, Finland. To see my curriculum vitae, please click here.

My current research interests revolve around applied probability and quantitative finance. More specifically, they include ambit stochastics, limit theorems for stochastic processes, market microstructure, Monte Carlo methods, statistical modelling of high-frequency financial data, and volatility modelling (both implied and realised) and forecasting.

I lead the Imperial Network of Excellence in Probabilistic Methods and Modelling and I am also a member of the Stochastic Analysis Group at Imperial.

I co-organise the SIAM-LMS Conference on Mathematical Modelling in Finance 2017 at Imperial College London on 31 August–2 September 2017.

During the academic year 2017–2018, I teach the following modules at Imperial:

- M5MF10 Quantitative Risk Management (MSc in Mathematics and Finance, core, Autumn term)
- M5MS13 Pricing and Hedging in Financial Markets (MSc in Statistics, elective, Spring term)
- M5MS12 Financial Econometrics (MSc in Statistics, elective, Spring term)
