Bio
Hugo Lambert is a natural scientist interested in the atmospheres and climates of the Earth and other planets -- particularly rocky planets orbiting other stars. He is an associate professor in the Department of Mathematics at the University of Exeter. He obtained his PhD from Atmospheric, Oceanic and Planetary Physics at Oxford and subsequently worked at the University of California, Berkeley and the UK Met Office before moving to Exeter.
He is one of the organisers of the Environmental and Sustainability Interest Group.
Research interests
His research uses data science techniques to carry out comparisons between model predictions and observations. Current work concerns the understanding and comparison of different approximate representations of small-scale processes known as "parameterisations" that must be used by numerical models due to computational constraints. Parameterisations are believed to be responsible for the majority of uncertainty seen in the prediction of future climate change on Earth, for example, but the group of parameterisations of a given process we have is arbitrary. The aim is to build and apply interpretable data science techniques that allow us to compare structurally different parameterisations of a given process to each other and observations or a physical model of the same process. it will then be possible to assess the contribution of different types of parameterisation to overall modelling uncertainty and determine whether the parameterisations we have properly represent our uncertainty in physical processes.
