Dr Dehaan has a BSc (Hons) degree from University of New South Wales (UNSW), specialising in geology, and a PhD from UNSW, which involved refining strategies for processing hyperspectral imagery in terrains of spectral and spatial variability.

Dr Dehaan worked in the private sector preprocessing, calibrating and analysing hyperspectral and airborne video data before holding his current position as Senior Lecturer in remote sensing and geographical information systems (GIS) in the CSU School of Environmental Science.

Dr Dehaan's research has concentrated on the use of hyperspectral remote sensing and GIS for environmental, agricultural, geological and other landscape mapping applications with current research focusing on the use of remote sensing and GIS to improve decision making in agricultural and environmental areas.
