Niall Gandy

Dr Niall Gandy BSc MSc PhD

Lecturer in GIS


Summary

Niall is a palaeo-glaciologist and GIS specialist, primarily lecturing in GIS at Sheffield Hallam University.

About

Niall joined Sheffield Hallam in 2022 as a Lecturer in GIS. Niall completed a PhD at the University of Leeds in 2020, using the BISICLES ice sheet models to simulations the British-Irish Ice Sheet, with a thesis titled “The Role of Ice Streams in the Demise of the British-Irish Ice Sheet”. Prior to the PhD, Niall completed at undergraduate degree at the University of Sheffield and remained for an MSc in Polar and Alpine Change.
