After being assigned at the same hospital as Chief Resident in the same year, he studied “spinal cord injury and spinal cord regeneration” as a “research fellow” alongside Prof. Charles Tator, M.D., at the University of Toronto Faculty of Medicine in 1998-1999. After returning from Canada in 1999, he was tasked by the Ministry of Health to establish a Field Hospital and to work in cooperation with the Turkish Red Crescent Society at Hakkari, Şemdinli for two months. Following this assignment, he volunteered to work for the 1999 Marmara Earthquake relief effort.

He became an Associate Professor of Neurosurgery in 2004. He earned the title Doctor of Science (Ph.D.) by completing a doctorate program on Advanced Neuroscience between 2000-2005, at Hacettepe University Institute of Medical Sciences. He joined the project for autologous stem cell therapy in human spinal cord injuries with the Departments of Neurosurgery and Hematology at the Ankara University Faculty of Medicine. In 2009, he was appointed as Deputy Chief to the 1st Neurosurgery Clinic at the Ankara Numune Hospital, where he had been working.

At this hospital, in which he worked until 2010, he supervised and attended complex cranial, pediatric, spinal, trauma and vascular neurosurgery operations. He continued his academic research at Ankara University, Department of Anatomy and research laboratories of Ankara University and Hacettepe University for the purpose of developing strategies for complex spinal surgery operations.

With his research on spinal cord injuries and spinal anatomy, he won many awards such as the Acibadem Hospital Medical Research Award, 1st Place in 2000, Turkish Neurosurgical Society Dr. Mahir Tevruz Scientific Research Award, Tübitak and Brain Research Society Wheyt Award in 2001, Turkish Neurosurgical Society Hamit Ziya Gokalp Young Neurosurgeons Research Award, 2nd Place in 2002, Turkish Neurosurgical Society Yildiz Yalcinlar Scientific Research Award in 2004.
