Katie on ResearchGate

As Principal Scientist, Katie focuses on MSC’s strategic research projects, and leads research on how fisheries may adapt in the face of climate change.  
She works with the MSC team of data scientists and researchers, and together they explore and strengthen the scientific evidence that supports our program. 
Katie has expertise in market-based incentives, data-poor fisheries assessments, impact assessments and measures of biodiversity. 
Katie has a broad range of interests across multiple disciplines, with the common thread of finding new and better ways to use available science to inform marine management and sustainable seafood markets.  
Previously, as Project Scientist at The National Center for Ecological Analysis and Synthesis (NCEAS), University of California Santa Barbara (UCSB), Katie contributed to the creation of the Ocean Health Index - a framework for the assessment of the delivery of sustainable societal goals from healthy oceans. 
Over the past decade her projects, in collaboration with researchers around the world, included developing tools to better manage fisheries that are data limited, and forensic techniques to monitor seafood traceability.   
Ph.D. (2012) in Fishing and Fisheries Sciences Management, University of Aberdeen.  

Thesis - “Predator-prey interactions and indicators of the impact of fisheries on fish species diversity”.  

MSc. & BSc. (2004) in Integrated Ecology, Evolution, Systematics and Population Biology, University of Rome – Sapienza.  

Thesis - "Feeding ecology and reproductive biology of Argentina sphyraena and Glossanodon leioglossus (Teleostea, Argentinidae) in the Central Tyrrhenian Sea".
