about

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 volcanoes.

Crustal Structure at Uturuncu volcano, Bolivia

I am currently using seismicity to image the crustal structure of Uturuncu volcano, Bolivia.

Icequakes and DAS at Rutford Ice Stream, Antarctica

I am also currently developing methods of using Distributed Acoustic Sensing (DAS) to investigate icequake processes at Rutford Ice Stream, Antarctica.
