Hi! I am a seismologist and geophysicist, and in my research, I use spatio-temporal patterns of microseismicity and simple modeling approaches to understand how seismogenic system organize, and the physical processes underpinning it.
I am currently working as a postdoc in the Seismology Laboratory of UC Santa Cruz. I work mainly with Emily Brodsky, investigating how regular earthquakes and tectonic tremor interact, to understand how fault system can organize into regular seismicity patterns.
Research and project interests
- Understanding the complexity of seismic systems by studying interactions
- The architecture, dynamics and evolution of fluid circulation pathways in faults and volcanoes
- Seismic/accoustic signals as ways to understand minute geophysical processes
- Numerical and experimental modeling to study all geophysical and planetary processes!

We model the unsteady flow of fluid in permeable faults with elementary permeability valves distributed in a channel. As valves break open and heal in response to local pressure conditions, they produce bursts and migration of activity, similar to tremor observations in subduction zones.

In there, we characterize the source properties of low-frequency earthquakes detected in Guerrero, Mexico. We find that, although their moment magnitude varies on orders of magnitude, their duration seems to be independent of it, displaying a characteristic scale. This could hint at a source process different from a classical earthquake rupture.
