Research Interests

My current research primarily deals with visuospatial attention, specifically by considering the problem as one of dynamically routing visual information through the ventral stream. The model performs this dynamic routing via the dendritic interaction of a subcortical control signal and feedforward projections, resulting in a subset of the visual information being projected to early inferotemporal cortex, while maintaining local spatial relationships in an object-centred reference frame.
