Profesional skill
As Seismologist, my expertise is on earthquake analysis (probabilistic and deterministic), earthquake physics and modeling of earthquake rupture and strong ground motion using high performance computing resources, oriented for applications in earthquake science, hazard assessment and risk mitigation. As Engineer, my expertise is on structural dynamic analysis (linear and non-linear) of buildings, bridges and other civil structures subjected to dynamic loads such those from earthquakes and winds. In particular, I have a good understanding on earthquake-resistant structural design and seismic safety of future and existing structures.
These advanced knowledge provide me the capability to understand and assess all the different phases from the earthquake source, wave propagation, ground motion and site effects to detail evaluation of seismic hazard, building response and risk mitigation. But also provide me with the capability to understand the fundamental inputs for hazard maps, risk assessment, ground motion prediction equations (GMPE), response spectral designs, building codes, construction practices and catastrophe models (Hazard, Inventory, Vulnerability and Loss) and ultimately, with the ability to understand and evaluate the scientific and engineering principles that support all these models.
I use numerical techniques such as Finite Difference, Spectral Element (high order Finite Element) and Discrete Element Methods for physics-based earthquake simulations, and Finite Element Methods for structural analysis of civil structures. I have a good understanding of the formulations and theoretical foundations of these numerical methods.

Research interest
My research is primarily the investigation of the physics of the earthquake source rupture, near-source ground motion and the implementation of seismology research advancements into Earthquake Engineering knowledge, with the final goal to promote the integration between Earthquake Scientists and Earthquake Engineers. Most of my research is developed through theoretical and high-performance computational modeling. Within this framework, I am interested to tackle problems related to:.
- Complexity of the earthquake source process
- Off-fault damage (tensile crack and plastic yielding)
- Source- and propagation-dominated ground motion phenomena
- Source inversion and pseudo-dynamic source models
- Geodynamic and earthquake cycles
- Ground Motion Prediction Equations
- Characterization of earthquake dynamic loading for evaluating earthquake response of Engineering Structures and risk mitigation.
- Multi-scale earthquake/engineering approach to couples the scale of engineering (structures, lifelines, etc) with the matching scale in earthquake rupture models
- Coupling earthquake rupture models with tsunamis
- Induced Seismicity: Investigation of explosion triggering earthquakes and Geothermal induced seismicity by means of physics-based earthquake models
- Development of earthquake numerical algorithms for High Performance Computing
