Dr Gary George Wells

Associate Professor

Department: Mathematics, Physics and Electrical Engineering

Ee Gary Wells255I joined Northumbria University as an Anniversary Research Fellow in 2013. I gained a PhD in Physics from Nottingham Trent University In 2009, where I won the Sharp, SID 2009, best student award, for my work on wrinkling liquid surfaces using dielectrophoresis forces.

Before joining Northumbria I served two years as a Devices and Materials Researcher in the displays laboratory at Hewlett Packard in Bristol.
