I work in pelagic ecology, specially on intermediate trophic level species in the open-ocean and the mesopelagic zone. I am particularly interested in diel vertical migration and carbon export mediated by zooplankton and micronekton, and how these processes are shaped by physical oceanographic processes and climate. I use echosounders and net sampling to study zooplankton and micronekton composition, distribution and behavior. For this reason, active acoustics is the discipline to which I devote most of my time, developing new methods to gain insight on pelagic ecosystems and providing open-source software for the scientific community.
