Numerical models of fluid flow provide the means to bridge the gap between geophysical observations (e.g. seismological, temperature, pressure data) and the fundamental processes that govern the production and movement of fluids within subduction zones. I develop numerical models constrained by laboratory measurements on recovered sediments, as well as field measurements from seafloor observatories that provide a continuous record of temperature and pressure throughout the seismic cycle.

Projects to date have focused on Costa Rica, with new projects focused on the Hikurangi margin, New Zealand, and the Japan trench, NE Japan.
