Alex Jarman

Alex Jarman

PhD student involved in the CCCEP (Centre for Climate Change Economics and Policy) research project entitled 'On the Provision, Reliability, and Use of Hurricane Forecasts on Various Timescales', sponsored by reinsurance company, Munich Re. Alex was awarded his doctorate in 2014.

He graduated with a Physics degree from the University of Auckland, followed by a Masters in Applied Meteorology at the University of Reading where he was awarded a NERC studentship. His research interests include forecast evaluation and decision-making with forecast information, nonlinear time series analysis, and the physics and predictability of weather and climate.

Trevor Maynard

PhD student in the Statistics Department at LSE. Trevor completed his thesis in 2016.

Thesis title:  ‘Extreme insurance and the dynamics of risk’.

Senior Visiting Fellow to CATS 2009-2012.

Deputy head of exposure management at Lloyd's of London. He has authored or edited the majority of Lloyd's published reports on Climate Change. He represents Lloyd's on various climate change related initiatives including ClimateWise, UNEPFI, Geneva Association and the London Climate Change Partnership. Trevor is on the management board of the Lighthill Risk Network, a collaboration between Lloyd's and others in the insurance market which seeks to join up the business world with that of academia. He also sits on the Industry Advisory Board of the Industrial Maths Knowledge Transfer Network. Until 2010 he sat on the Maths Strategic Advisory Team for the Engineering and Physical Sciences Research Council. Trevor has previously worked for Royal and Sun Alliance, Friends Provident and Mercer. He is a Fellow of the Institute and Faculty of Actuaries and has bachelor and master of science degrees in pure mathematics from the University of Warwick.

Ewelina Sienkiewicz

PhD student in CATS

She was awarded NERC Doctoral Training Grant and began her thesis in October 2012. Her provisional title is 'Internal Consistency as a Tool in Analysis and Application of Nonlinear Simulation'. Research interests include: model error in forecasting non-linear systems, predictability, statistical analysis of large computer models, model development and forecast evaluation, decision support using weather and climate models.

Ewelina graduated with a Master of Science degree in Computer Science and Econometrics from the University of Szczecin in Poland. She became a PhD research student in the Department of Statistics at LSE after working as an analyst in various sectors and companies including the Scottish Government and Ford of Europe.

Edward Wheatcroft

PhD student in CATS

He began his thesis in October 2010 as part of the NERC-funded RAPID-RAPIT project, a collaborative project led by the National Oceanography Centre, Southampton. He thesis title is 'Improving predictability of the future by grasping probability less tightly'. Ed will study the relationship between models and reality in the context of climate change. The research will work towards the design of ensemble experiments which can evaluate the spatial and temporal scales on which complex climate models can potentially provide quantitative information about the future real world climate.
