Dr Mark Lethbridge has research interests in manned and unmanned aerial surveys of mammals using trained human observers and/or thermal imagery. Mark has over 24 years of experience in undertaking aerail surveys and has trained over 20 government and non-government staff. Unmanned thermal camera missions are best flown at night, hence the use of Military-style UAVs with redundant systems. Mark has also developed a number of autodetection algorithms.

Mark has also focussed heavily in his research on animal movement behaviour with a lifetime of work on wallaby, camel and goat movement. Of late his work has focussed on the development of 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.

Restoration ecology and decision support tools have dominated Mark's research work in the past. Together with Dr Micheal Westphal, Mark developed OPRAH, a landscape restoration prioritization algorithm used in NRM.

Pest species and over-abundant species management (e.g. kanagroo commercial harvest) and pest impact work currently dominates Mark's research.

With native species over the last 10 years he has also developed a spatially-explicit individual-based Population Viability Model (PVA) that also models pedigree structures to determine in-breeding depression at landscape scale. Here Mark is well-known for his work on Yellow-footed Rock-wallabies.

Mark works with and resides on the advisory panel of AERF, a conservation and research NGO in India.
