Dr Niall Gandy BSc, PGCert, MSc, PhD
Lecturer in GIS
Summary
Niall is a palaeo-glaciologist and GIS specialist, primarily lecturing in GIS at Sheffield Hallam University.
About
I joined Sheffield Hallam in 2022 as a Lecturer in GIS. Before that, I completed a PhD at the University of Leeds in 2020, using the BISICLES ice sheet model to simulate the British-Irish Ice Sheet, with a thesis title "The Role of Ice Streams in the Demise of the British-Irish Ice Sheet". I stayed in Leeds for a postdoc position using coupled Climate-Ice Sheet models. Prior to my PhD, I completed an undergraduate degree at the University of Sheffield, and remained for an MSc in Polar and Alpine Change.
