Steering Committee

The "End of an Arc" program is managed by representatives from each of the three founding institutions:

and supported by three other rotating members (one from each founding institution), most notably on the project evaluation committee.


Mark Jellinek, Professor, UBC

Dr Mark Jellinek

Although products of similar physical processes, the distinguishing feature of the inner solar system planets and moons is that each has evolved differently. Why such profound differences developed is not obvious and is a major motivation for my work. My research constructs knowledge about how different styles of planetary mantle convection emerge and how these flows govern volcanism, magnetic field generation and climate change over long (106-109 year) time scales. I also address how observations of volcanic processes and their products can be applied to constrain the dynamics of magmatic systems within a broader context of the evolution of planets. My work addresses big, challenging questions encompassing diverse classes of problems in physical volcanology, volcano eruption dynamics, magmatic processes, geodynamics, planetary science, climate change science and basic fluid dynamics. I address these using a combination of observational (e.g. field, geochemical, laboratory, and remote sensing) and modelling (experimental, theoretical, and numerical) studies. See Mark´s UBC page.

My research focuses on understanding magma degassing from magma at depth to the surface. I am interested in integrating both dissolved and exsolved volatile behaviour during magmatic processes (e.g. differentiation, degassing). I have studied the exsolution path of magmatic volatiles by combining 1) the volatile (H2O, CO2, S, Cl, F) concentrations dissolved in melt inclusions and in the groundmass glasses. 2) the volatile (especially S) solubility by HT-HP experiments. 3) the volcanic plume composition (trace elements, S, Cl, F). 4) the volcanic SO2 flux (DOAS measurements) and 5) the chemistry of the fumaroles gases. See Séverine´s LMV page.


Glyn Williams-Jones, Associate Professor, SFU

Dr Glyn Wiliams-Jones

My research group focuses on physical volcanology and the processes controlling persistently active volcanoes. Our current research integrates the study of geophysical signatures with geochemical and remote sensing data to investigate precursory signals to volcanic activity and the physicochemical mechanisms that trigger eruptions. We use a variety of geophysical and geochemical techniques (e.g., gravity, differential GPS, gas flux, satellite remote sensing) to study volcanoes in the Americas, Europe, South East Asia and Hawaii.
