Main interests

In my research group we are dedicated to the study of the dynamics, diversity and conservation of coastal marine ecosystems and how they are influenced by oceanographic, climatic and human processes 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 to quantify recruitment variability as well as oceanographic observations along large sections of the central coast of Chile.   We are also interested in the underlying process of dispersal and connectivity among populations of invertebrates and fish in the costal ocean, which determines the dynamics of meta-communities and set the context for any successful conservation and management strategy. Much of this research combines empirical, theoretical and modeling efforts conducted in collaboration with students, postdocs and colleagues of different disciplines.  Finally, much of our work is dedicated to generating the scientific knowledge to improve conservation of marine biodiversity. Here we focus primarily on defining the conditions that control the efficacy of marine reserves and on the roles of biodiversity on ecosystem functions at regional to global scales. Thus, our studies are usually of interdisciplinary nature, including ecologists, population geneticists, physical oceanographers, climatologists and mathematicians.
