I'm an Assistant Professor in the departments of Neurology & Neurosurgery, and Biomedical Engineering at McGill University of Montreal, Canada. I work at the McConnell Brain Imaging Centre of the Montreal Neurological Institute. My research involves automated anatomical segmentation and atlasing in a neurosurgical context. Computerized image processing techniques, such as non-linear image registration and model-based segmentation, are used to automatically identify structures within the human brain. These techniques are applied to a large database of magnetic resonance (MR) data from normal subjects to quantify anatomical variability. In image guided neurosurgery (IGNS), similar techniques provide the surgeon with computerized tools to assist in interpreting anatomical, functional and vascular image data to effectively plan and carry out minimally-invasive neurosurgical procedures.

The Image Processing Lab

There is quite a number of people in the lab working on segmentation techniques and their application to analysis in Image Guided Surgery, Multiple Sclerosis, and Epilepsy.

Current Projects
