Welcome to Geophysics @ UCD!
Our research focus is on the nature of complexity in crustal systems. It has become evident in recent years that the strength of and stress within the crust is highly heterogeneous over a broad range of scales. This heterogeneity is, in general, highly discontinuous and usually scale invariant. This realization has far reaching consequences for a broad spectrum of crustal phenomena. These include: Seismic wave propagation; Crustal imagery; Fluid- Rock interactions; Earthquake and stress diffusion; Earthquakes triggering. Our research focuses on these topics.
