Research interests

My research interests lie primarily in behavioural ecology, with a focus on predator-prey dynamics and their impacts on trophic interactions. In South Africa, my studies focused on the behavioural interactions among large carnivores and large herbivores. Since relocating to New Zealand, I have expanded my research area to the behaviour of invasive mammalian predators and its application on predator control.  I have worked with NGOs in New Zealand on conservation education for an extended period of time. The experience has also aroused my interests in the social aspects of the Predator Free 2050 movement.
