Research
My research focuses on the population and movement ecology of freshwater fishes, including anadromous species, in temperate and tropical rivers. I investigate both fundamental and applied questions to generate knowledge that can contribute to the management and conservation of freshwater fishes, sustainable inland fisheries, and enhanced public awareness about the status of studied organisms.
To conduct my research, I use telemetry technologies (e.g. radio, acoustic) to track wild, free ranging fish in freshwater. To synthesize information and test hypothesis based on the collected data, I use cutting-edge statistical models (e.g. mark-recapture, hierarchical, state-space models) fitted using both frequentist and Bayesian approaches.
I am fortunate to be involved in a variety of research projects and collaborating with very talented researchers:
1) Behaviour and survival of sockeye salmon (Oncorhynchus nerka) during their return migrations to the Fraser River, Canada
2) Cumulative effects of stressors and management actions for Fraser River sockeye salmon
3) Movement ecology and entrainment vulnerability of bull trout (Salvelinus confluentus) and burbot (Lota lota) in a hydropower reservoir
4) Migration and fishway passage of catfish in the Madeira and Xingu Rivers, Amazon Basin
5) Movement ecology and habitat use of arapaima and arowana in floodplains of the lower Purus River, Amazon Basin
