Shi-Ting Li, MD, PhD



Chairman of Dept. Neurosurgery, XinHua Hospital, Shanghai JiaoTong University School of Medicine

Director of the Cranial Nerve Disease Center of Shanghai JiaoTong University

Leader of the Functional Neurosurgery Group, Shanghai Neurosurgical Association

Vice-chairman of Chinese Neurological Minimal-invasive Therapy Association


In the recent 10 years, Dr. Li performed about 8000 cases of MVD procedures for hemifacial spasm and trigeminal neuralgia, and many other kinds of operations. Based on this experience, he published 100 peer-reviewed papers with the focus on cranial nerve disorders. He firstly reported the "Sympathetic-bridge hypothesis" regarding the pathogenesis of hemifacial spasm. Following this hypothesis, his team discovered a novel waveform for intra-operative monitoring during MVD, namely, ZLR. 


He was invited as a coordinator and oral presentation speaker in varied international conferences. He has given speeches in at least 20 international conferences and several hundreds of Chinese conferences.  In 2015, he was invited by Springer as the editor-in-chief of "Microvascular decompression surgery", and this new book now attract lots of attention in this field.

Wilkinson .JPG

Marshall Wilkinson, M.D.

Dr. Wilkinson was born and raised in Vancouver, B.C. Canada. After completing his honours degree in physiology at the University of British Columbia he undertook postgraduate studies and earned both Masters and Doctorate degrees. Dr. Wilkinson’s thesis work investigated the neurophysiological regulation of the febrile process. His graduate record was highlighted by earning the nationally recognized Medical Research Council of Canada Studentship award. His postgraduate training was conducted at the University of Calgary in Alberta Canada where he was a Fellow of the Medical Research Council of Canada and the Alberta Heritage Foundation for Medical Research. During this period he developed research programs in the field of neuro-immunology in combination with his post doctoral training in neurophysiology.
In 1993 Dr. Wilkinson received the prestigious Medical Research Council of Canada Centennial Fellowship to conduct research studies in neuro-immunology. At the conclusion of this Fellowship he was offered a position in the Department of Clinical Neurosciences at Foothills Hospital in Calgary Alberta to provide intraoperative neuromonitoring services for a variety of surgical procedures including microvascular decompression for hemifacial spasm.
In 2002 Dr. Wilkinson joined the Health Sciences Centre in Winnipeg Manitoba to supervise the intraoperative neurophysiological monitoring program for the Section of Neurosurgery. He continues to develop new techniques to limit surgical morbidity to the nervous system and is involved in several research initiatives such as the pathophysiology of hemifacial spasm

Dr. Sekula is known internationally and nationally for his development of microvascular techniques, which provide patients with improved outcomes, reduced complications, and easier recoveries. He has performed more than 1,500 procedures for patients with trigeminal neuralgia, hemifacial spasm, and other cranial neuralgias. He has also developed techniques in brain surgeries of all types that reduce patients’ hospital stays to one or two days without the need for the intensive care unit after the procedure.
He has been recognized with numerous honors, including The American Association of Neurological Surgeon’s Young Investigator Award, The Trigeminal Neuralgia Association Fellowship Award, and Pittsburgh Magazine’s “40 Under 40” and “Best Doctor’s” Award.
Dr. Sekula received his undergraduate degree from the University of Virginia and his medical degree from Georgetown University School of Medicine. Following a surgical internship and residency in neurological surgery, he completed advanced training in minimally invasive neurosurgery and a fellowship with neurosurgical pioneer, and former University of Pittsburgh Department of Neurological Surgery chairman, Peter Jannetta, MD. Following his training, he became assistant, and then co-director, of the Cranial Nerve Disorders Center with Dr. Jannetta in Pittsburgh.
Dr. Sekula is also a renowned teacher of neurological surgery and is a frequent lecturer nationally and internationally. He has been awarded the annual faculty teaching award by the department’s residents in 2015 and 2016. Dr. Sekula has authored or co-authored many original journal articles and book chapters, and is coeditor of the textbook Microvascular Decompression Surgery, a comprehensive look at MVD surgery, widely accepted as an effective remedy for cranial nerve hyperexcitability disorders including hemifacial spasm, trigeminal neuralgia, and glossopharyngeal neuralgia.
