And he is currently serving as the President of Korean Spinal Pain Society and Korean Society of Complementary and Alternative Medicine. He is also the President of Asian Australasian Federation of Pain Societies. He is serving or served as the Editorial Board of Acta Anaesthesiologica Taiwanica (Ma Tsui Hsueh Tsa Chi), the official journal of Taiwan Society of Anesthesiologists, Editorial Board of Journal of Clinical Rehabilitative Tissue Engineering Research (China), and Editorial Board of Chinese Journal of Anesthesiology, the official journal of Chinese Society of Anesthesiologists. He is Honorary Member of Taiwan Pain Society and Member of National Academy of Medicine of Korea. He was the President of Korean Spinal Pain Society, the President of Korean Society of Anesthesiologists, the President of Korean IASP Chapter and the President of World Society of Pain Clinicians. He published more than 250 articles

He has published many predominant papers resulting from his researches and clinical experiences in reputable journals and is inventing other device. He had been awarded Outstanding Research Award from Interventional Spine Center of Stanford School of Medicine twice consecutively in 2002 and 2003 when he had worked as a Interventional Spine Research fellow and Visiting Scholar in Physical Medicine and Rehabilitation department of Stanford University for three years from 2000 to 2003. In addition, he won Best Paper Award at 11th Annual Scientific Meeting of the International Spinal Injection Society(ISIS) and Young Investigator Fellowships Award of International Federation of Clinical Neurophysiology in 2003 and received HAKI Award for the Best Paper at the 11th congress of the International Musculoskeletal Laser Society in 2004.

He has contributed to numerous publications which are due for publication in well-respected American medical journals, and he has assisted in presenting those papers nationally. He is currently working on more than 3 other research projects.

Dr. Lee invented a percutaneous disc decompression device to treat chronic axial low back pain. It is the first percutaneous medical device with a navigatable tip which can access all potentially symptomatic areas of the typical herniated disc. With this technological advance, interventional spine doctors will be able to treat the many patients with chronic low back pain without open surgery. His new device promises significant benefits to patients and the health care system, both medically and economically. Patients undergoing minimally-invasive back surgery will have precision treatment of their ailments, less procedural risks, shorter hospital stays and quicker recovery times. We are also in the process of developing new medical devices for the treatment of spinal stenosis.

Christof Birkenmaier is an academic spine surgeon at Ludwig Maximilians University, Munich, Germany since May 2000. He is board-certified in Orthopaedics, Trauma and General Surgery and currently heads the spine team and the osteology section of the department. During his training, he has worked in the UK, the USA (UCSF) and Germany. The spectrum of his work in spine spans from minimally invasive procedures, full-endoscopic spine surgery, navigation and robotics, the surgical treatment of fractures and tumors to major deformity correction and osteotomies. With regards to osteology, the specialty clinics of the department diagnose and treat the complete spectrum of metabolic and genetic bone disorders, from simple osteoporosis over Paget's disease to a number of rare diseases. The combination of spine surgery and osteology brings with it a special expertise in the treatment of aging and osteoporotic spines. Dr. Birkenmaier is actively involved in a variety of research projects and regularly publishes articles in peer-reviewed scientific journals.

Senem Simsek received her BS degree in Biology from Hacettepe University in Turkey and MSc degree in Biotechnology from Middle East Technical University in Turkey. Her early scientific history of Clinimacs CD34(+) hematopoietic stem cell preparation for autologous and allogenic transplantations under the supervision of Prof. Dr. Fikret Arpaci in Gulhane Medical School Bone Marrow Transplantation Center was her greatest milestone in her career. During her PhD studies, she joined to A. Francis Stewart’s Genomics Department TU Dresden c/o International Max Planck Institute. She actively worked in the Technology and Development division towards mammalian systems. She established innovative conditional mutagenesis strategy and the tool in mouse embryonic stem cells available to identify epigenetic networks directed and control differentiation and cell lineage commitment. It explored at the same time mammalian RNA polymerase termination elements, their physical distance and the role of DNA between splicing acceptor and polyadenylation signals. She earned her PhD degree under the honored umbrella of a DAAD scholarship. She has another remarkable achievements were recorded in Danish Stem Cell Society towards future clinical stem cell applications in Assoc. Prof. Vladimir Zachar’s Laboratory of Stem Cell as a postdoctoral and lecturer fellow. They contributed the research field of pluripotency by their significant finding that the intersection of Notch and Shh pathways play notable role in maintenance of pluripotency and self renewal of human embryonic stem cells. Her research was supported by Otto Monsted Research Travelling Awards Foundation for Keystone Hypoxia and ISCRR Meetings in 2010. This work was published in Differentiation high peer review scientific magazine as symposium abstract. Lastly, she has a proven track record of responsibility, and integrity in human pluripotent stem cell (hiPSC/hESC) research, disease remodelling and drug therapy in best medical school in USA, Weill Cornell Medical College in Shuibing Chen lab. Her research got acceptance in top-tier journal where she is first author. She was invited to introduce this work in the United Nations in 2013. In 2015, she got full scholarship to establish 3D printing of pancreas model in Sabancı University.

The vice director of MISS in CMDA, vice chairman of spinal endoscopy
group in CPAM. Major in minimal invasive spinal surgery for more than 20 years, and specialize in spinal endoscopic surgery. The goal and type of surgery are minimal invasive, easy and various operation according to the patients, less time, less complication.
Have explored and developed the treatment of lumbar degenerative disease, spinal infection, spinal tuberculosis, spinal tumor, spinal deformity by minimal invasive methods. Successfully treated about 4000 cases with lumbar degenerative disease since 2003 by spinal endoscopic surgery, and about 1000 cases with spinal infection(including spinal tuberculosis). The most surgeries operated in one day were up to 17cases(PELD).
One of pioneers who attempted to provide various medical service by internet. One of the most popular doctors in the internet, and won the most-viewed online(collective hits 13.000.000, zhangxifeng.haodf.com) in “Good doctor” the biggest doctor-patient communication Platform. And also the moderator of “lilac garden” the biggest E-education Platform in China.

Dr. Oertel is particularly interested in the development of new minimally invasive surgical techniques in spine surgery. He acts as Professor of neurosurgery at the University of Saarland Germany and Director and Chairman of the Department of Neurosurgery at the University Hospital of Saarland, Homburg, Germany. He published more the 100 original papers, numerous book chapter on new minimally invasive surgical techniques. He presented his work in more than 400 presentations and participated as faculty in more than 50 workshop worldwide. His personal experience includes almost 7000 surgical procedures. At the Department of Neurosurgery about 3 – 400 endoscopic procedures are done per year.
