I am a seismologist, using geophysical observations, novel data processing methods and simple geophysical models to improve our understanding of fundamental earth system processes. My current expertise is primarily in elucidating geophysical processes at glaciers and geothermal systems. To do this I use conventional seismometer technology as well as developing new methods utilising data from Distributed Acoustic Sensors (DAS) and dense seismic node arrays. I am currently a Leverhulme Early Career Fellow.
