A life-long interest in wildlife and natural environments led me back to scientific research after professional diversion to work in Information Technology. In 2009, I completed a PhD at James Cook University in Townsville where my research focussed on the behaviour of marine turtles in near-shore foraging grounds and the animals’ vulnerability to being struck by fast-moving boats. I was subsequently appointed an Adjunct Research Fellow at JCU. In that role I have continued to run several independent projects and undertake new collaborative work with TropWATER and CMES research colleagues.

Research Interests

My research focusses broadly on wildlife behaviour and ecology. I am particularly interested in marine species and coastal birds, and in seeking new insights to conserve their vital habitats and minimise harmful impacts of human activity on wild species.

I am also very interested in developing and enhancing fieldwork techniques, technologies and analytic methods for investigating the behaviour of elusive wild species.

I enjoy collaboration, mentoring and co-supervising graduate students and I’m always open to discussing ideas for new projects.

Current Projects

Together with several colleagues I am involved in long-term studies of marine turtles at focal sites along the Queensland coast, investigating spatial behaviour, diet, body condition, and genetic linkages. We are using a diverse array of electronic telemetry methods, stable isotope analysis, GIS and statistical approaches, relying on R for most of the data wrangling. (I admit to being a technology nerd and R-evangelist at times.)

The avian side of my work currently comprises a multi-season study of Pied Imperial Pigeons including photo-monitoring their nest-attendance patterns at remote island breeding sites. I am also developing a citizen-science project to collect new data on this species along the mainland coast of Queensland (
