Piotr Fryzlewicz

Professor of Statistics, LSE

I am a Professor of Statistics in the Department of Statistics at the London School of Economics.

I currently hold an EPSRC Fellowship on the topic of New challenges in time series analysis.

I also currently serve as Joint Editor of the Journal of the Royal Statistical Society Series B

My research interests: multiscale modelling and estimation, time series (especially nonstationary time series), change-point detection, high-dimensional statistical inference and dimension reduction, randomised algorithms, statistical learning, data visualisation, statistics in finance, statistics in the social sciences, statistics in neuroscience
