Audrey Valls

Ph.D., Zoology

2011-2014 Junior Research Fellow (University of British Columbia)

Audrey Valls’s doctoral research explored methods for understanding, modeling and predicting feeding relationships between marine species. She proposed a novel index, using a mathematical model to represent food webs and identify ecologically important species. She also looked at how to use knowledge in fish feeding behavior to predict fish diet composition. Her research highlighted the usefulness of digital and open-access information repositories in marine ecology and fisheries science. Audrey is now working on coupled human-nature systems models at the Centre for Biodiversity Theory and Modelling.
