About Me
Publications
My research focuses on developing and applying new techniques to analyze large seismic datasets in order to better understand earthquake rupture processes and their links to earthquake hazards. I am broadly interested in making advances in field of earthquake science by leveraging concepts from big data and scientific machine learning alongside high-fidelity physical models.
