My primary expertise lies in the understanding of animal behavioural ecology. I am particularly interested in animal movement patterns and behaviour, and how these are linked to their habitat and environmental variability. My PhD research involved quantifying sex-specific patterns of bottlenose dolphins in regards to abundance, demographic parameters, home ranges and habitat use. I have previously worked on dugong ecology, and explored the fine-scale movements and habitat use of dugongs with respect to the tidal cycle and vessel traffic. I have also assisted projects on various dolphin and whale species (incl. sperm whales, humpback whales, Indo-Pacific humpback dolphins and spinner dolphins). Through my research, I have an interest in spatial analyses, habitat modelling and population modelling.

My PhD research explored sex-specific patterns in abundance, population parameters, home ranges and habitat use of Indo-Pacific bottlenose dolphins (Tursiops aduncus) in Bunbury, Western Australia. Since 2007, research has focussed on the Bunbury dolphin population through the South West Marine Research Program. Bunbury has one of Western Australia’s largest commercial shipping ports and is a popular location for recreational water activities and dolphin-targeted tourism. My study area expanded 540 km2, extending from Busselton to Binningup. Photo-identification images of dolphin dorsal fins were obtained from systematic boat-based surveys carried out across all austral seasons.

The primary aims of my research were to:

  • Estimate sex-specific patterns in abundance, apparent survival and temporary emigration of dolphins and to investigate fluctuations in population parameters with environmental conditions;
  • Investigate sex-specific differences in home range size for adult dolphins, and explore whether dolphins could be partitioned into groups based on home range size;
  • Examine the influence of biotic and abiotic factors on the seasonal spatial distribution and habitat use of adult male and adult female dolphins.
