I have research interests in animal movement, distribution and abundance modelling, as well as plant and animal habitat modelling.

I have carried out a lifetime of research on wallaby, camel and goat movement. Of late I have developed algorthims using in adverse conditioning satellite collars that adapt to individiual behaviours and work with, rather than fight the animal in terms of moving it into or away from an area. This work is in collaboration with Dr Ben Allen, Univesrity of Southern QLD.

The use of human observers or Remotely Piloted Aircraft (RPA) in the aerial surveying of mammals for distribution and abundance estimates, primarily depends on the time of day or night the target species is most active. I have 25 years of experience in undertaking aerail surveys and have trained over 22 government and non-government staff. I also fly large RPAs and HD thermal camera missions at night researching pest and native distributions but at times use 2xHD thermal cameras during the day on crewed aircraft. Auto-detections are an important focus oif my research.

Restoration and threatened spp. ecology and decision support tools have dominated my research work in the past. Together with Dr Micheal Westphal, I developed OPRAH, a landscape restoration prioritization algorithm used in NRM. Just recently I led the translocation of the threatened Purple Spotted Gudgeon and now research better ways to monitor them.

Pest species and over-abundant species management (e.g. kanagroo commercial harvest) and pest impact work currently dominate our 2022/23 research.

I continue to develop spatially-explicit individual-based Population Viability Models (PVA).

Apart from research, I am the Managing Director of Ecoknowledge, own Animal Tracking and continue as an Adjunct at Flinders Uni. I also advise on policy for government, work closely with two Aboriginal communities on projects and advise AERF, a conservation NGO in India.
