About

Jamie Farquharson

I'm an experimental and computational geoscientist with a passion for volcanology. Broadly speaking, I investigate volcanic processes across a wide range of spatiotemporal scales in order to understand the mechanisms that give rise to complex eruption phenomena observed in nature. I have a background in experimental rock deformation and computational volcanology, coupled with hands-on machine engineering and programming experience. Past and current research topics include (1) Micro- to meso-scale rock deformation and fluid flow; (2) Reactive fluid flow in geologic systems; (3) Eruption triggers and dynamics; and (4) External forcing of volcanic hazards, including the impacts of climate change. I'm also a firm believer in open-access, a principle I advocate for in my roles as founder and Editor-in-Chief of Volcanica, Secretary of the Free Journal Network, and Senior Advisory Council member of EarthArXiv. Found out more about these projects below. Feel free to check out my research interests or access my publications. I am Professor at Niigata University, Japan.
