I joined the Department of Psychology as a Reader in October 2018 having previously been a Senior Lecturer at the University of Birmingham.
I have been working in the field of Visual Perception for nearly 30 years but have always combined this with a strong interest in Computer Vision and Machine Learning including Neural Networks.
My research focuses on human visual perception with applications in computer vision and robotics. I also study changes in visual perception in older adults.
My main focus is on the perception of visual texture (second-order vision) and how this enables humans to distinguish between changes in illumination from changes in the material properties of surfaces. This is combined with an interest in shape-from-shading, the role of shadows in object perception, and depth perception.
In Computer Vision the same mechanisms that we think are used by humans to separate illumination and material changes can be used by machines for the same purpose (intrinsic image extraction). Here I am also interested on how human edge and surface processing can be modelled with machine learning and deep neural networks to aid in the reconstruction of 3D shape from 2D images.
Older adults find it harder to see visual texture than younger adults and this may lead to difficulty in judging the shape of uneven surfaces such as steps. Here I am interested in how step markings might be manipulated to influence toe clearance in older adults.
