My research covers three main topics:
(1) The representation of space and motion in human vision. This has the aim of developing a model of space and motion perception in terms of nested frames of reference defined by the articulations of the body. The model has been expanded to incorporate orientation perception.
(2) The history of research in visual science, with the aim of providing an account the development of experimental methods in vision, particularly those concerned with stereoscopic vision.
(3) The relationship between visual science and visual art. This has the aim of fostering a closer association between the graphical language of art (particularly geometrical abstraction) and the interpretative language of science.
I am involved in active international collaboration with Prof. S. Finger, Washington University, St. Louis; Dr. B. Lingelbach, University of Aalen; Prof. H. Ono, York University, Canada; and Prof. Marco Piccolino, University of Ferrara.
