Reaching the end of this tenure in 2019, he retired from his duties as the Director of the Institute of Neuroscience and as a Member of the Faculty of Medicine. During his tenure at Marmara University, he supervised and accompanied surgical operations for complex cases from cranial patients to brain tumors (gliomas, meningiomas and hypophysis adenomas in particular), cerebral hemorrhages, Parkinson’s disease, trauma and vascular neurosurgery. He performed complex spinal surgery operations such as surgeries for spinal deformities (e.g. scoliosis and kyphosis), thoracoscopic spinal surgeries and sacral tumor surgeries. He conducted research and experimental studies on therapy and regeneration in spinal cord injuries. Between 2019-2020, currently He continues his clinical practice and surgeries along with his local and international academic studies, from his private clinic and Istanbul Brain and Spine Center.

He has attended numerous national and international courses and meetings as an instructor and speaker, was a guest speaker in over 100 events and conferences.
