Bio

I joined MEAS during Fall 2019 as a Researcher and Lab Manager for the new Geochronology Laboratories applying Optical Stimulated Luminescence (OSL) and Terrestrial Cosmogenic Nuclides (10Be/26Al and 36Cl).

My research focus in Active Tectonics and Neotectonics, Earthquake Geology/Paleoseismology,  and Tectonic Geomorphology. I study deformation through the interaction between active and seismogenic structures with the surface and how it affects surface processes. To be able to constrain deformation in time, I apply the Geochronology techniques available in MEAS Geochronology Laboratories. This allows me to quantify deformation rates (long term or short term slip-rates, which is build up on several earthquakes) or obtain the timing of individual slip (each earthquake occurrence). I have also conducted research in uplifted paleo sea-level references (marine terraces) to identify vertical crustal deformation and decode the tectonic and GIA components associated to them.

Presently, I am researching the Mw 5.1 Sparta 2020 earthquake in North Carolina. I have active research projects on active faulting at several locations in California, along the San Andreas, San Jacinto, Banning faults, and in Eastern California Shear Zone (Camp Rock Fault)  and Nevada (Paleoseismology of the Pleasant Valley Fault) and slip-rates of associated mountains fronts. I am also conducting research in Portugal, as a continuation of the research initiated during my PhD.
