I am a cellular and molecular neurobiologist by training but I have made a career change from neurobiology to cognitive neuropsychology and swapped lab bench with microscope for MRI scanner.
My work is concerned with understanding the structural and functional organization of visuospatial attention in the human brain by using data from brain imaging with sub-acute stroke patients with a variety of visuospatial deficits as well as with healthy controls.
My previous research focused on understanding neural architecture of spatial attention by decomposing the neuroanatomy of several visuospatial disorders based on voxel-based morphometry (VBM) analysis and diffusion tensor imaging. This work has demonstrated that different pattern of grey matter lesions and the laterality of white matter disconnections in individual neuropsychological patients, are key to predicting the cognitive deficits resulting from stroke.
My current research stems from my interests in understanding the mechanisms of functional recovery after damage to the neural networks supporting visuospatial attention. I am currently working on several projects aimed at examining whether and how individual differences in functional organization of spatial attention predict behavioural consequences of brain damage. I am also involved in projects addressing whether information acquired as part of routine clinical diagnosis could be used to predict recovery versus persistent cognitive deficits following stroke. Most recently my work extends into understanding brain connectivity underlying self-prioritization.
