Dr Jowan Barnes

Research Fellow

Department: Geography and Environmental Sciences

I am a postdoctoral research fellow attached to the PROPHET project, part of the International Thwaites Glacier Collaboration. This involves improving the representation and understanding of physical processes in ice flow models. Current areas of interest in my work include inversion procedures, the use of different basal sliding laws, and melt rate parameterisation.

I graduated from the University of Reading with an MMath degree in 2014, and went on to study for a PhD in oceanography with the National Oceanography Centre and Newcastle University, where I graduated in 2019. During this time, I modelled the effects of geothermal heating on the abyssal ocean, with a particular interest in hydrothermal vent systems as a source of heat at the seabed.

I have now turned my mathematical modelling experience towards investigating one of the fastest changing glaciers in Antarctica.
