Christine (Chris) is a postdoctoral researcher in the School of Veterinary Science, University of Queensland (since March 2011). Chris’ research interests fall under the broad umbrella of population ecology and dynamics of marine organisms, with current focus on large marine vertebrates; including sharks, rays, whales and dugongs.  She employs a suite of techniques, including acoustic telemetry, mark-recapture analysis, molecular genetics and statistical modelling, to investigate what comprises a population, how this changes in space and time, and the application of this knowledge to conservation and fisheries management.

Chris studied zoology, marine biology and molecular ecology for her undergraduate at James Cook University in Townsville (1998).  She then worked on several projects investigating molecular ecology of coral reef organisms at JCU and AIMS before undertaking a PhD on the population ecology of leopard sharks at the University of Queensland (2009).

Chris currently splits her time between conducting research and small child-wrangling. 

Projects

  • Population ecology of leopard sharks Stegostoma fasciatum on the east coast of Australia: migratory movements and genetic effective population size estimates (funded by Sea World Research and Rescue Foundation).
  • Photo-identification of leopard sharks for investigating migratory movements and longevity: Spot the Leopard Shark.
  • Modelling heterogeneity concerning the detectability of humpback whales during land-based and aerial surveys to improve humpback abundance estimates (funded by Australian Marine Mammal Centre). This project is part of the east Australian humpback population abundance project.
  • Abundance and demography of giant mantas, whale sharks, seven-gills sharks and grey-nurse sharks using mark-recapture methods.
