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 include:

- Statistical modelling of high-frequency financial data and market microstructure
- Volatility modelling and forecasting
- Monte Carlo methods in finance
- Limit theorems for stochastic processes

During the academic year 2017–2018, I taught 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)
