Prof. Lenny Smith

Associate

As well as being a Professor in Statistics at LSE, Lenny is also Director of the Centre for the Analysis of Time Series (CATS) and Senior Research Fellow at Pembroke College, Oxford.

Background

Lenny obtained a PhD in Physics at Columbia University (USA) in 1987.

He has held grants funded by many bodies, including ONR (US Office of Naval Research) and NOAA (US National Oceanic and Atmospheric Administration), the European Commission and UK Research Councils.

Two successful projects – DIME and REMIND – were funded under the UK EPSRC Maths Faraday programme, and a current project, NAPSTER (Nonlinear Analysis and Prediction Statistics from Time Series and Ensemble forecast Realizations), is a UK NERC Knowledge Transfer grant.

Lenny was active in the formation of strategy for THORPEX (he was co-author of the Socio-Economic Impacts Chapter).

In recognition of his mathematically-coherent user-relevant contributions, the Royal Meteorological Society awarded Professor Smith its Fitzroy Prize.
