Bio

Born in Trinidad and Tobago, Dr. Mohammed earned the President’s Gold Medal and Open Mathematics Scholarship which entitled him to 7 years free University education anywhere in the world, based on his A’level examination results.  He did 5 years of medical school at University of the West Indies in Trinidad and Tobago graduating with honors in anatomy, physiology and biochemistry, and was awarded the most outstanding clinical student for his year. He then completed an 18 month internship, and subsequently worked as a house officer in various surgical subspecialties.  In 2007 Dr. Mohammed started a Master’s program at the University of Toronto in the Institute of Medical Science.  In 2009 he started neurosurgical residency at the University of Toronto.  In his PGY 3 year he obtained the First Place William J Horsey Prize for most outstanding clinical research in Neurosurgery.  In PGY 4 he designed and completed an in-folded spine Fellowship involving both orthopedics and neurosurgery in the three major academic spine centers in Toronto (Sunnybrook Hospital, St Mike’s Hospital and Toronto Western Hospital).  In PGY 5 he was awarded the Alan R Hudson neurosurgery residency teaching award.  During residency Dr. Mohammed had an active role in the Advance Trauma Life Support (ATLS) courses, for which he was an instructor for over 30 courses and then became a certified Course Director.  Also during residency Dr. Mohammed was a member of the medical board of the Spina Bifida and Hydrocephalus Association of Ontario.  Dr. Mohammed completed his neurosurgical residency program in 2015 and then embarked on a formal post graduate Spine Fellowship combined at the Sunnybrook Hospital and St Michael’s Hospital under the University of Toronto Spine Program from 2015-16. During his time in training he published 9 articles, one book chapter, several oral presentations and over 20 poster presentations at various national and international meetings.

In 2016 July, Dr. Mohammed assumed his post as a Staff Neurosurgeon at The Ottawa Hospital, Civic Campus and as Assistant Professor with University of Ottawa.  Dr. Mohammed has an avid interest in education in neurosurgery and within a year at the Ottawa Hospital became the Director of Undergraduate Education for the Division of Neurosurgery and Spine Fellowship Director for the combined orthopedics and neurosurgery adult spine fellowship.

Dr Mohammed current scope of practice includes General Neurosurgery, cranial tumors, trigeminal neuralgia, traumatic brain injury, in addition to his main subspecialty of Complex Spinal Surgery. With regards to Spinal surgery, the focus is on Minimally Invasive Spine Surgery techniques incorporated in a practice of Oncology (Cancer), Acute Trauma/ Poly trauma, Degenerative Disease, Degenerative Scoliosis, Intradural Tumors, Spinal Tumors, Acute Spinal Cord injury management, Spinal Vascular Lesions, Vertebroplasty/Kyphoplasty.

Director, Neuromodulation and Functional Neurosurgery
Principle Investigator, Sachs Lab

Division of Neurosurgery

Administrative Assistant:
Lauren Stead
lstead@toh.ca

Bio

Dr. Sachs is Director of Neuromodulation and Functional Neurosurgery at The Ottawa Hospital, and Assistant Professor of Surgery at The University of Ottawa Brain and Mind Research Institute. Prior to medical school, he completed a Bachelor of Science at McGill University in Physiology and Math, and a Master of Arts at York University in Applied Mathematics researching mechanisms of human edge detection. During his neurosurgery residency at The University of Ottawa, he participated in the Clinical Investigator program, performing neurophysiology and brain computer interface research in non-human primates. After residency, he completed a two-year fellowship in functional neurosurgery and spine surgery at Stanford University.

He is Principle Investigator of the Sachs Lab, which investigates how real-time feedback of brain signals can be used to help individuals with movement disorders. Using brain-computer interface (BCI) technology, participants are able to use only their brain to control external effectors such as a robotic arm or an object in a virtual reality scene. For individuals with certain motor disorders (e.g., Parkinson’s Disease, focal dystonia, essential tremor), learning to use the BCI may induce plasticity that provides some recovery from symptoms. For individuals with severe disabilities due to central nervous system trauma or amyotrophic lateral sclerosis, the BCI may provide an alternative communication channel to restore some independence.

Dr. Sachs’ scope of practice includes complex spine management of spinal deformity, tumors, and trauma; and neuromodulation for neuropathic pain.  His cranial neurosurgery practice focuses on deep brain stimulation for movement disorders, microvascular decompression, and intra-axial brain tumors.
