Lisa Koski completed her Ph.D. in Clinical Psychology at McGill University in 1999. Her thesis research, conducted at the Montreal Neurological Institute, contributed to understanding the role of the frontal lobes in controlling attention.

From 1999-2004, Dr. Koski was a postdoctoral fellow and visiting professor at UCLA where she performed neuropsychological assessments at the Neurorehabilitation Research Unit while training in neuroimaging and neurostimulation techniques.

Dr. Koski returned to Montreal in 2004. Positions held include Associate Professor of Neurology & Neurosurgery at McGill University and Investigator with the Brain Repair and Integrative Neuroscience program at the Research Institute of McGill University Health Centre.  For over ten years Dr. Koski maintained a research laboratory based around CIHR-funded investigator-initiated projects on stroke, neurocognitive disorders, and multiple sclerosis. She has collaborated on research projects involving measurement of cognitive functions in diverse projects spanning conditions such as dementia, stroke, multiple sclerosis, HIV-associated neurocognitive impairment, and mental disorders.

In August 2023 Dr. Koski retired from her position at the MUHC, joining Neurotherapy Montreal to contribute to their Memory program.
