I studied in London, starting with Physics (BSc) and Medical Physics (MSc) before moving towards computational neuroscience and psychology to take on a research project on mechanisms of dynamic visual perception for my PhD (2008). After that, I worked on related themes as a post doctoral researcher in interdisciplinary vision groups. The first of these was at a Vision Research lab at McGill in Montreal (2009-2011) and then later for a Neuroscience institute of the French CNRS in Marseille (2011-2015). I spent a summer as a visiting scientist at the RIKEN Brain Sciences Institute in Japan training in the use of fMRI (Summer 2012). I joined Bournemouth University in 2016 both to teach and develop my research themes. I will also be a part of the Interdisciplinary Neuroscience Research Group in the Faculty of Science and Technology.
My expertise is in the use of visual psychophysics and eye movement recordings in combination with computational or mathematical approaches to try and shed light on how the human brain makes sense of dynamic scenes. In particular, I am interested in motion perception, spatial and temporal integration and the effect of mirror symmetry on vision. My current research questions include (1) How does the brain very quickly decide which parts within a viewed, moving scene to combine and which parts to process as separate entities? (2) How do our eyes effortlessly extract information about object symmetry in scenes and what role do eye movements play in this dynamic selection process? (3) How do the spatial scales within visual scenes impact on our interpretation of such scenes? In other words are we better at 'seeing', for example, smaller objects at certain distances (which determines size on the retina) and larger objects at different distances? For these question, eye movement recordings and visual pyschophysics detection and discrimination tasks with controlled synthetic stimuli are typically used alongside statistical and signal processing models. I have ongoing collaborations with the University of Western Australia, CNRS Paris and Marseille, and Royal Holloway University of London and other groups.
