PhD project title: Seismo-volcanic source mechanism in hydrothermal systems
I am a final year PhD student at the Institute of Geophysics and Tectonics. My research project is funded by the University of Leeds Research Scholarship and is supervised by Prof. Jurgen Neuberg and Dr. Dan Morgan.
The focus of my research is on the very-long period (VLP) seismic signals, an understudied type of volcanic seismic signals that can give us a great insight into volcanic system geometry and fluid flow inside the volcano. The current focus of my research is on VLP signals observed at White Island/Whakaari volcano and trying to explain them by modelling wave propagation in the poroelastic medium.
My research also included:
i) a study on the influence of seismic network configuration on moment tensor inversions, i.e. determining the effect of station distribution around a volcano on our ability to correctly resolve the source mechanism of the observed signals.
ii) a study on a complex, static displacement of a very long period seismic signal observed at Soufriere Hills volcano, Montserrat
I enjoy teaching geophysics very much and have been very lucky to be able to demonstrate on several modules in the School of Earth and Environment at the University of Leeds including:
Time Series Analysis - A basic mathematical foundation for spectral analysis and filter theory
Numerical methods and Statistics - Use of MATLAB and Python for numerical differentiation and integration and for statistical analysis
Computing and Programming in Geoscience - Use of UNIX system and programming in MATLAB
Inverse Theory - Solving inverse problems in geophysics using Python/MATLAB
Fundamentals of Geophysics
Maths support tutorials - Developed maths support tutorials for MSc students
