Valerie has a PhD in Statistics from the University of London (Imperial College) for a thesis on multidimensional point processes. She joined UCL in 1978 and has been a professor since 1992, becoming an Emeritus Professor in 2018 . She was Head of Department from 1996-2002 and again from 2010-2011, and was President of the Royal Statistical Society in 2011 and 2012. Currently she chairs the Scientific Steering Committee of the Isaac Newton Institute for Mathematical Sciences in Cambridge, and the Biometrika Board of Trustees. She is a member of Council of the Bernoulli Society and is the London and New Zealand Mathematics Societies Forder Lecturer for 2018.
Applied probability: broadly, the development and application of stochastic models, including i) the generic development of models for point processes and determination of their properties; ii) development of models for spatial and spatio-temporal processes arising in the physical sciences, and especially in hydrology (eg soil moisture and precipitation); iii) models for applications in the life and medical sciences, focussing particularly on population processes, epidemics and the transmission dynamics of infection and information; iv) models for random networks and for the dynamics of processes evolving on them.
