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

My current research interests include ambit stochastics, limit theorems in probability, market microstructure and limit order books, realised volatility, simulation methods, statistical inference for stochastic processes and random fields, and stochastic volatility. I am a member of the AHOI Network and the Stochastic Analysis Group at Imperial.


During the academic year 2016–2017, I teach the following modules at Imperial:

Enrolled students can access the teaching materials on Imperial Blackboard.
