Best neurosurgeons: TOP 583 doctors

Dr. Serdar Kabatas, graduated from Trakya University Medical Faculty, Edirne/Turkey in 1997. He became a neurosurgeon-specialist- in 2003 and then gained an award for postdoctoral fellowship in Spinal Cord Injury (SCI) and Neural Stem Cell (NSC) at Harvard Medical School in 2007. He has spent most of his scientific carrier in the study of SCI related stem cell applications either experimentally or clinically, stem cell clinical applications in hypoxic-ischemic encephalopathy, traumatic brain injury, cerebral palsy, autism spectrum disorders, periferic nervous system injuries, cell-based approaches for intervertebral disc regeneration, dentritic stem cell vaccines regarding brain tumours, trigeminal neuralgia, aneurysm surgery, etc. Among his achievements are the prediction of neural and anatomical abnormalities of the gastrointestinal system resulting from contusion SCI and functional multipotency of NSCs- its therapeutic implications- in USA. 

In addition to his scientific interests, he is the President of Society of Stem Cell and Cellular Therapies in Turkey. He is also member of AANS, CNS, Society of Neuroscience, Turkish Neurosurgical Society, Society of Nervous System Surgery and Turkish Spine Society. He is the chief editor of Journal of Nervous System Surgery. He had been teaching neurosurgery to medical students at the Baskent University, Turkey from 2008 to 2013. Between 2013 to 2015, he was the chief of Neurosurgery Department in Private Reyap Hospital, Tekirdağ. Curently, he has been the chief of Department of Neurosurgery in University of Health Sciences Turkey, Gaziosmanpaşa Training and Research Hospital, Istanbul, Turkey since 2016. He was awarded as the first candidate for Specialization Thesis (2004) and Board Exam (2011) in Turkey, respectively. He was also awarded as research project regarding Stem Cell Applications in Rat Model (2013) in Turkey. He has more than 100 publications in peer-reviewed international journals with around 1300 citations. His h-index is 21 in google scholar and 17 in web of science.
