Dr. Louis Collins

Biography

Louis Collins is a Professor in the Department of Biomedical Engineering at McGill University and holds additional appointment as an Associate Member in the Department of Neurology and Neurosurgery. His research focuses on computerized image processing techniques, specifically non-linear image registration and model-based segmentation. These tools are employed to automatically identify structures in the human brain and quantify anatomical variability. Dr. Collins investigates neuroscientific applications of three-dimensional digital image processing methods to aid in disease diagnosis, prognosis, and image-guided surgery. His work includes processing large databases of magnetic resonance data from normal subjects to assess normal anatomical variability in pediatric, young adult, and elderly populations. Additionally, he utilizes these techniques to quantify global and regional brain atrophy in patients with multiple sclerosis, exploring morphological changes associated with diseases such as schizophrenia, Alzheimer's, and dementia. His specialized skills also extend to image-guided neurosurgery, providing surgeons with computerized tools that assist in interpreting anatomical and vascular image data, thereby enabling effective planning and execution of minimally invasive neurosurgical procedures. Automated atlasing is a crucial aspect of his work, particularly in treatments such as thalamotomy and pallidotomy for Parkinson's disease.
