Introduction
My research in Marine Geology and Geophysics explores the complex interactions between tectonic structures and sedimentary processes. I utilize high-resolution geophysical techniques to constrain how active faulting and submarine landslides shape the seafloor and influence geohazard assessment. I aim to enhance our understanding of earthquake histories, regional tectonics, and the potential for geological hazards.

Most seafloor slopes are shaped by a gravity sediment transport process known as submarine mass wasting, frequently associated with seismic activity on tectonically active margins. Although poorly understood and difficult to reach, offshore active fault systems and seafloor mass wasting pose a risk to infrastructure and coastal populations. Thus, m...
Repeated mass transport deposits (MTDs) are identified within fault-bounded basins of the Outer California Continental Borderland and are likely associated with intermittent seismicity and/or sea level variations of the Quaternary. These types of mass transport and episodic slope failures may be capable of triggering tsunamis, which may pose a haza...
Volcanic seamount chains on the flanks of mid-ocean ridges record variability in magmatic processes associated with mantle melting over several millions of years. However, the relative timing of magmatism on individual seamounts along a chain can be difficult to estimate without in situ sampling and is further hampered by Ar 40/Ar 39 dating limitat...
The releasing stepover in San Diego Bay is characterized by a pull-apart basin geometry between the southern termination of the Rose Canyon fault around downtown San Diego and the Descanso fault offshore along the USA-Mexico coastline. Although the step between these two strike-slip faults is considered too large for through-going rupture, the comp...
The 8°20’N seamount chain extends 170 km west from the fast-spreading East Pacific Rise (EPR), parallel to the Siqueiros fracture zone, and provides a unique opportunity to study off-axis volcanism and melt source variability. While dating seamount volcanism is challenging using geochemical methods, the relative age of magmatic constructions can be...
The 2016–2017 Amatrice-Norcia seismic sequence was triggered by the reactivation of a complex NNW-SSE trending, WSW-dipping normal fault system cross-cutting the Umbria-Marche fold and thrust belt near M. Vettore. This fault system produced clear and impressive co-seismic ruptures on normal faults in the hangingwall of the M. Sibillini thrust, wher...
