Ivar Mendez OC[1] is a Canadian neurosurgeon and neuroscientist who is a professor of surgery at the University of Saskatchewan. He is known for his work in cell transplantation for Parkinson's disease and the use of remote presence robotics in neurosurgery and primary health care. In December 2022, Mendez was appointed an officer of the Order of Canada for his pioneering work in the use of remote telemedicine and robotics to revolutionize the delivery of health and patient care.[2] Dr. Mendez is the Director of the Virtual Health Hub.[3]

Mendez served as the F.H. Wigmore Professor[4] and Provincial Head of the Department of Surgery at the University of Saskatchewan and the Saskatchewan Health Authority from 2013 to 2022 for the Province of Saskatchewan. He also holds an appointment at the Department of Psychology and Neuroscience at Dalhousie University and he is one of the founders of the Brain Repair Centre.[5] He is also the president and founder of the Ivar Mendez International Foundation[6] that provides health and educational assistance to children in the Bolivian Andes. Mendez is a photographer and sculptor[7] and has published four books of photography.

Biography

Mendez was born in La Paz, Bolivia and immigrated with his family to Canada as a teenager. He obtained a BSc degree from the University of Toronto and then an M.D. from the University of Western Ontario (UWO). He did a neurosurgical residency training in London, and was certified in Neurosurgery from the Royal College of Physician and Surgeons of Canada in 1994 and from the American Board of Neurological Surgery[8] in 1996. He became a fellow of the American College of Surgeons in 1998 and became a member of the College Board of Governors[9] in 2015. His interest in regenerative medicine led him to obtain a PhD in Anatomy and Neurobiology from the UWO his PhD thesis was on "Neurotransmitter Interactions in Nigral Grafts".[10] He did a postdoctoral fellowship at the University of Lund in Sweden under the supervision of Anders Björklund.[11] In 2014, Saint Mary's University (Halifax) in Nova Scotia awarded Mendez a Doctor of Science (honoris causa) degree for his contribution to Neuroscience and he was inducted a Fellow to the Canadian Academy of Health Sciences.[citation needed] In 2016, Mendez received the Government of Canada Public Service Award of Excellence for the use of remote presence robotic technology to improve healthcare in the Canadian North.[citation needed] In December 2022, Mendez was appointed an officer of the Order of Canada for his pioneering work in the use of remote telemedicine and robotics to revolutionize the delivery of health and patient care in Canada and worldwide.[2] Dr. Mendez is the Director of the Virtual Health Hub.[3]

Scientific contributions

He pioneered the technique of multiple grafts to restore dopamine input to the parkinsonian mammalian brain.[12][13] This technique was translated into clinical trials in patients with Parkinson's disease and showed long-term survival of those grafts.[14][15][16][17] He also pioneered the use of Glial Derived Neurotrophic Factor (GDNF) in combination with fetal cells in humans.[18][19][20] Mendez invented a transplantation delivery system to inject cells into the human brain.[21] With his team, he performed the first long-distance brain surgery robotic telementoring in the world by using a robotic arm to mentor neurosurgeons located 400 km away. [22] He is also pioneering the use of remote presence devices to deliver health care in remote locations.[23][24][25] In 2015, Mendez and his team printed the first 3D brain for planning deep brain stimulation surgery.[26][27][28][29][30] Research in 3D brain printing led in 2016 to the development of a virtual reality (VR) brain for medical education and surgical planning applications.[31][32][33] In 2020, Dr. Mendez and his remote presence technology team pioneered the use of telerobotic ultrasonography for abdominal and obstetric sonography.[34][35] This technology was used to provide prenatal ultrasound to pregnant women living in COVID-19 outbreak communities.[36]

Humanitarian contributions

Mendez has established a Canadian charitable organization, the Ivar Mendez International Foundation,[6] to provide nutrition, dental care and art program to children in remote locations of the Bolivian Andes.[41]

Awards

  • Officer of the Order of Canada[1]
  • Queen Elizabeth II Platinum Jubilee Medal[42]
  • Government of Canada Public Service Award of Excellence 2016[43][44][45]
  • Queen Elizabeth II Diamond Jubilee Medal[46]
  • Humanitarian of the Year Award, Canadian Red Cross - Atlantic Region[47]
  • Ten most influential Hispanics in Canada[48]
  • Dr. John Savage Memorial Award[49]
  • Royal College Medal Award - Medalist in Surgery[50]

Artistic endeavours

He has published four books of photography [51] and has had several exhibitions of his photography and sculpture [52] In October 2003 He sculpted a bust of Canadian Neurosurgeon Dr. Charles Drake was installed outside the front entrance of University Hospital in London, Ontario where Drake practiced medicine. The statue was unveiled by American Actress and Singer Della Reese whose life was saved by Drake following an Aneurysm in October 1979.[53]
