Fieldwork, expeditions in wild places and events like rocket launches challenge and inspire. These experiences are also a critical part of the work my group does on problems in volcanology, magmatic processes, surface processes, planetary science and climate change over decadal, millennial and longer time scales. Here are images from a selection of field excursions over the years. Please also see my publications


A volcano-seismic test of our "Magma Wagging" model for pre-eruptive volcanic tremor at Popocat├ępetl Volcano, Mexico (2014). Collaborator: D. Roman (DTM, Carnegie Institution)

A radar and IR study of turbulent entrainment and mixing into volcanic jets at Sabancaya Volcano, Peru (2018). Collaborator: F. Donnadieu (UCA, France)

Silicic magmatism

Characterizing the rheological controls over the character of mafic-silicic magma interactions at Tuolomne Meadows, CA (2010).

Developing quantitative field constraints on the dynamics of silicic magma chamber rejuvenation and overturn along the Maine coast and in the sierras (2001, 2004, 2007 and 2010). Collaborator: R. Wiebe (UC Davis)

Surface Processes and Martian Analogue Studies

Testing a new method for identifying and distinguishing the erosional fingerprints of pressurized subglacial channelized flows from fluvial drainage systems in remotely sensed topographic and image data, Devon Island, Nunavut (2016 and 2017). Collaborator: G. "Oz" Osinski (UWO)

Exploring quantitative analogues for the origins of high and low slope Martian gullies, channel initiation and downstream evolution in polygonal terrains and bedrock controls over subglacial channelized drainage, Axel Heiberg Island, Nunavut (2019). Collaborators: G. "Oz" Osinski (UWO) and former PhD students A. Grau Galofre (ASU) and S. M. Chartranc (SFU)
