My research reflects a broad generic interest in marine ecology, with particular interests in the understanding of the mechanisms underlying the adaptation and evolutionary processes of marine organisms to their environment. Consequently, my research interests are varied, ranging from marine hydrodynamics, biogeography, larval transport and dispersal, and connectivity processes.
More specifically, my research has mainly focus on the effects of environmental heterogeneity, particularly hydrodynamic phenomena, on larval behavior, larval transport, larval dispersal, settlement, recruitment and population dynamics.
I am also interested in, and had the opportunity to worked with through different collaborations, related topics in the framework of conservation and marine biology: seabird reproductive ecology, mangrove propagules dispersal, use of internal and pop-off satellite tags to study wide movements and migration dynamics in marine organisms, satellite products for oceanography, monitoring and predicting climate change impacts on marine systems; marine spatial planning and Marine Protected areas network design principles.
I strongly believe in applied science, and increasing communication between science and policy makers, such that the best available science is incorporated into resource management and policy at local, regional, national and international levels.

Biological-physical interactions: hydrodynamic and particle trajectory modeling, ichthyoplankton and zooplankton ecology, ecological modeling, fisheries recruitment variability.
Water movement, including currents, tides, and upwelling, is a critical factor driving the ecology and evolution of marine life. Many marine organisms are adapted to or exploit particular hydrodynamics characteristics of its habitat. I am studying biological and bio-physical modelling of, primarily, the early-life stages of fish but also zooplankton. I am interested in the physical and biological mechanisms controlling (1) growth and survival, (2) larval dispersal, (3) larval settlement, (4) and connectivity between populations.
