Dr Jowan Barnes

Research Fellow

School: Geography and Natural Sciences

I am a postdoctoral research fellow currently attached to the PRECISE project (PREdicting Changes in Ice Sheets on Earth), in partnership with collaborators in Copenhagen. My work focuses on using mathematical models to study processes of ice dynamics and how we can better represent them for future predictions of both Greenland and Antarctica. My interests include inversion procedures, basal sliding laws, calving, ice shelf basal melt and ice-ocean coupling.

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, from 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.

At Northumbria, I have previously been involved in the PROPHET project (PROcesses, drivers, Prediction: modelling the History and Evolution of Thwaites), part of the International Thwaites Glacier Collaboration, as well as PROTECT.
