Camilla Mathison


Camilla is a part time PhD student working in Exeter at the Met Office. Camilla joined the Met Office in Forecasting research in 2002 where she spent the first four years working in the high resolution and land group where she completed a Masters in Applied Meteorology at Reading University. In 2006 she moved within data assimilation to the Middle Atmosphere group where she worked on ozone and developed an interest in climate timescales which prompted a move to climate research in March 2009.

Since joining climate research Camilla has worked on the ENSEMBLES project, AMAZALERT and the HighNoon project. This PhD, partly funded by the HELIX project, hopes to continue the progress made in understanding the changing water resources for Northern India and the Himalyas in the HighNoon project.

Camilla has recently passed her viva with minor corrections.

Research interests

The South Asia region is interesting because of its diversity varying from glaciated mountains to lowland deltas, some of the wettest regions on earth  to dry arid regions,. A large river network and enormous irrigation systems. This region is dependent on agriculture and irrigation. All of these aspects together with  a large and rising population make this region an ideal case study for understanding the impacts of climate change and how these interact with each other.

The HighNoon project started this work and it was continued through the HELIX project.
