Quantitative Marine Ecology for Fisheries and Ecosystems
Marine quantitative ecologist and fisheries scientist working across observations, data, models, and decision-relevant evidence.
I study how marine populations and fisheries respond to environmental variability, fishing pressure, and ecosystem change. My work integrates ecological theory, biological and fisheries observations, oceanographic information, statistical modelling, and reproducible scientific computing.
My main study system is the Humboldt Current System, with particular emphasis on the north-central stock of Peruvian anchovy (Engraulis ringens). I also work on pelagic fisheries, fleet dynamics, multivariate stock indicators, and spatio-temporal analysis.
