Research interests

As a researcher in geophysics, my main research interest lies in developing novel methodologies for seismic imaging. The goal of my research is to improve our ability to image the Earth's subsurface with high resolution and accuracy, while being able to assess the uncertainty of the retrieved models. Passionate about programming, I try to do so by developing new algorithms for geophysical data analysis and inversion, as well as exploring the use of machine-learning techniques to enhance our understanding of the Earth's interior.

I am keen on dealing with observational data, and I always like to apply the fruits of my research to real-world problems. So far, I have mainly focused on surface-wave tomography tasks, but I also have an interest in statistical seismology and in accurately detecting coherent signals in seismic records. Recently, I have also delved into the application of optimal transport in geophysics, an emerging topic that I plan to explore further during my time here at ANU.
