I have been at the University of Plymouth since 2018 as an academic member of staff teaching on the geology programmes. My research is focussed on understanding tectonics, active faulting and earthquakes, particularly focussing on earthquake dynamics and interaction.

Since February 2021, I am UKRI Future Leaders Fellow and my project is "Quake4D - building physics-based, geologically-rich models for investigating earthquake interaction and seismic hazard", which will run for the next 4 years. This project will combine high-quality geological data with start-of-the-art computer simulations to generate a new approach to simulating synthetic earthquakes and quantifying seismic hazard.

Research interests

My PhD research focussed on the central Apennines of Italy, which is one of the most seismically active areas in Europe. I used a combination of structural geology, numerical modelling and geochemistry to investigate historical earthquakes, fault interaction and earthquake dynamics. During my PhD, I spent 4 months in Japan (as part of my JSPS fellowship), hosted by Proj Shinji Toda, developing a new approach to modelling Coulomb stress changes resulting from earthquakes. 

My Future Leaders Fellowship builds on the research from my PhD and the understanding I have developing of the natural variability of faults and earthquakes. The motivation for my project is that seismic hazard assessment is currently reliant on present-day measurements of slip rate and historical records of past earthquakes. However, recurrence times of large earthquakes often exceed the available historical record, and slip rates vary through time, which makes the current approach to seismic hazard assessment flawed. To rectify this, as it is not possible to gain more historic observational data, we must instead make use of simulations of synthetic earthquakes. Quake4D will be a geologically-rich physics-based fault model and produce a synthetic catalogue of earthquakes by simulating every stage of the earthquake cycle over many millennia. This synthetic model will be validated against data from natural fault systems and used to extract information that is pertinent to probabilistic seismic hazard assessment. This will drive a step-change in our understanding of the variability of earthquakes over time.

I have also worked on earthquakes in the UK (Hicks et al., 2019), faults in California (Hughes et al., 2020) and earthquakes in Japan (Toda et al., 2016).
