About Tim

Tim is a behavioural psychologist who is interested in learning processes and their contribution to socially significant behaviour. He is interested in bridging gaps between basic and applied research.

He teaches in the University’s Behaviour Analysis Programme and is co-director of the University’s Scent Detection Research Group. Much of his research is cross-disciplinary, involving collaborations with biologists, chemists, and medical researchers.

Research Interests

Current Research
With support from the HRC, Tim and his collaborators are investigating dogs’ ability to detect lung cancer, and with support from MBIE, they are researching dog’s ability to detect invasive fish in waterways. They are also conducting research on learning processes relevant to scent detection more generally. Additionally, Tim and his students are conducting conceptual and basic research relevant to motivation and language in humans and other animals.
