Luke Marsden

Profile

I joined the University of Leeds as a PhD student in October 2016, where I work with Prof. Jürgen Neuberg and Dr. Mark Thomas. I am a volcano seismologist and numerical modeller interested in the link between magma ascent, deformation and seismicity observed at the surface. As magma ascends through a volcanic conduit, shear stress exerted on the conduit walls pulls up the surrounding edifice, whilst overpressure pushes it outwards. I combine flow and deformation modelling to quantitatively investigate the relative contribution of shear stress and pressure to observed deformation. I am also interested in discerning the key factors that control magma ascent dynamics, and how ascent dynamics evolve through time as a result of transient volcanic processes.
