Andy's research can be broadly categorized into four primary areas of specialization (i) the development of image-based deformation methods for the measurement of displacements, velocities, accelerations and strain fields in geotechnical and other solid materials [Dr. Take's software, geoPIV, written in collaboration with Dr. Dave White (University of Western Australia), is currently being used in over fifty research centres worldwide], (ii) geotechnical physical modelling [Dr. Take is the Vice-Chair of ISSMGE technical committee on physical modelling, TC104], (iii) the investigation of the influence of climate on the mechanisms of landslide triggering, and (iv) the unsaturated behaviour of geosynthetics in geoenvironmental barrier applications.
