Predator-prey model and the formulation of the functional response
For my Phd I was interested in identifying the dominant factors that can influence phytoplankton-zooplankton interactions. In particular, I investigated the effect of environmental heterogeneity in the water column on the predation process, and how this can play a role in the zooplankton enrichment paradox. I also studied how this heterogeneity impacts predation interaction when looking at different biological scales (i.e. from population to the community level).

Impact of environmental and anthropogenic forcing on salmon population persistence
My goal is to understand how the decrease in abundance of the spring and summer Chinook salmon stocks from the Columbia River has led to dynamics synchronization among stocks and increased sensitivity to environmental perturbations. I am investigating the potential role of cohort resonance to explain this phenomenon.

Impact of the California Central coast MPAs implementation on the abundance of rockfish species
I am involved in the assessment of the impact of MPAs establishment along the Central coast of California on the abundance evolution of several species of rockfish. I investigate how past fishing pressure, specific life history features and ontogenetic migration could influence the response of these species to MPAs establishment.

California Central Valley chinook salmon managment
I am working on the development of a life cycle model that aims at evaluating the impact of California’s state and federal water project operations and climate change on spring-run Chinook salmon populations of the California Central Valley. I have implemented an acoustic tagging experiment in order to estimate survival and movement rates of spring-run juvenile salmons throughout their migration to the Ocean. I am also using otoliths isotope analysis in order to get information on spring-run juvenile growth rate and the success of different freshwater rearing strategies in the adult population.
