Dr. Line Jacques was born in Quebec City. She attended pre-med at DEC Health Sciences, Cegep Levis-Lauzon (1980-1982), followed by her B.Sc. in Biology (1982-1985) from Laval University. She went on to complete her M.D. and M.Sc. simultaneously (1985-1990) at the University of Montreal, with a focus on neurophysiology research. She completed her Neurosurgery residency at the University of Montreal (1990-1996), with a keen interest in Neuromodulation and Peripheral Nerve surgery. She completed her fellowship in Peripheral Nerve Surgery in 1997 under the guidance of Dr. David Kline at the Louisiana State University.

After returning from her fellowship in Louisiana, she joined the Montreal University Health Sciences Group of Hospitals, and quickly transitioned to the prestigious Montreal Neurological Institute, where she established the Peripheral Nerve and Pain Surgery program. Her aptitude for teaching was quickly recognized and she was appointed the Director of the Neurosurgery Residency Program (10 years) at the Montreal Neurological Institute until leaving in 2014 for the sunny skies of California, and an opportunity to become the Director of the Peripheral Nerve and Pain Surgery Programs, and Professor of Neurosurgery at UCSF. She continues to have a strong focus on teaching and mentoring through her fellowship program, and working with aspiring young medical students.

She has numerous publications and book chapters, and is a peer reviewer or deputy editor for 13 different journals. In 2017, she was appointed the Vice-chair of the Department of Neurological Surgery in the School of Medicine at the University of San Francisco, and most recently, receiving the John Adams Endowment for Peripheral Nerve and Pain Research. She contributes tirelessly lecturing and teaching nationally and internationally, participates in clinical trials, and is currently the Chair of the Division of Spine and Peripheral Nerve (Peripheral Nerve Section). Her husband, Thomas Koszegi, spent 30 years in the medical device industry with a focus on Imaging and Neuromodulation therapies.

Free time is spent hiking with their 9 year old Airedale terrier Roxy venturing through the hills and mountains of California and beyond.
