Lines of Investigation:

In my research group we are dedicated to the study of the dynamics, diversity and conservation of coastal marine ecosystems, how they respond to climate change and are influenced by oceanographic, climatic and human drivers operating from local to regional scales.

One of my lines of research attempts to understand how species interactions, namely predation, competition and facilitation, are modulated by physical processes, which together drive the structure and dynamics of spatially structured coastal marine communities. This research combines traditional field experimental manipulations with observational studies on recruitment variability and oceanographic processes along the central coast of Chile.  A central issue in most of my research is understanding the consequences of larval dispersal and population connectivity on the dynamics and persistence of meta-communities, biodiversity and, especially, on our conservation and spatial management strategies. I also work on the empirical and theoretical study of the relationship between biodiversity and ecosystem function, as well as on the application of network theory to approach complex socio-ecological systems, because I believe these approaches offer us a venue to examine and anticipate consequences of global and climate changes on coastal marine ecosystems. Thus, much of my research combines empirical, theoretical and numerical modeling in collaboration with students, postdocs and colleagues of diverse disciplines.
