Professor Hilmar Gudmundsson

I’m interested in the processes controlling the flow of glaciers and ice sheets. I’m fascinated by how complex the behaviour of large ice masses can be, how glaciers respond to external changes in the environment, and how they in turn affect the environment around them.

I’m a physicist by background and my research takes a combined observational, numerical and theoretical approach to understand the processes governing the behaviour of glaciers.

I lead the Peak of Research Excellence The Future of Ice on Earth which is the UK’s largest group focusing on physical modelling of large ice sheets such as the Greenland and the Antarctic Ice Sheet. Of particular research interest is the possibility of abrupt changes in the cryosphere and the onset of unstable glacier retreat processes such as the Marine Ice Sheet Instability of the West Antarctic Ice Sheet and the Surface Elevation Mass balance Instability primarily associated with the Greenland Ice Sheet.

I'm currently involved with several large NSF, NERC and EU research projects: 

• TPACCs: Tipping Point in the Antarctic Climate Components, funded by the European Union.
• Protect: Projecting Sea-Level Rise: From Ice Sheets to Local Implications, funded by the European Union.
•  PROPHET: PROcesses, drivers, Prediction: modeling the History and Evolution of Thwaites, as a part of the International Thwaites Glacier Collaboration project, funded by NSF/NERC.
• OCEAN:ICE  Ocean-Cryospheric Exchanges in ANarctica: Impacts on Climate and the Earth System. Funded by the European Union
• PRECISE: PREdicting Changes in Ice Sheets on Earth, funded by the Novo Nordisk Foundation
