  • Geophysics (Seismology)



  • I earned my PhD at the University of Connecticut, USA specializing in global seismology. My work led to the proposal of a new structural configuration in the Earth's solid inner core that favours a hypothesis, in which the inner core growth is coupled to thermal heterogeneities near the core-mantle boundary by convection in the liquid outer core. Later I joined Instituto Superior Tecnico, Lisbon, Portugal and used seismic surface waves to construct one of the first countrywide shear wave velocity models of the crust to better constrain tectonics and seismic hazard. Also, I started working on the physics of intraplate earthquakes in the African continent there. During this time, I was also an Honorary Research Associate at University College London. Following this assignment, I worked at the University of Muenster in Germany, and conducted research on the fine-scale seismic structure near the Earth's inner core boundary. My work there led to the proposal of a non-linear growth mechanism, consistent with results of metallurgical experiments. At present, I am a Research Fellow in the School of Earth Sciences at the University of Melbourne, where I am developing computational tools to analyze seismicity in Victoria with an emphasis on Gippsland Basin.

Supervision Statement

  • My research interests are in solid Earth geophysics. I work on problems related to Earth structure, physics of earthquakes, and seismic hazard. At present, I am investigating microseismic events in Victoria, from which we hope to understand the origin and characteristics of seismic events, and stress conditions in the Earth's crust.
