Assoc. Prof. Oğuz Baran
Training, academic work and professional activities.
Biography
Assoc. Prof. Oğuz Baran was born in 1984 in Merzifon, Amasya. He graduated from Hacettepe University Faculty of Medicine in 2010. From 2010 to 2011 he served his compulsory service as a general practitioner at Merzifon State Hospital.
Between 2012 and 2018 he completed his residency at the Department of Neurosurgery of İstanbul Training and Research Hospital. His residency thesis, “Microsurgical anatomy of the cerebellar peduncles”, was awarded the Dr. Aysima Altınok Residency Thesis Prize of the Turkish Neurosurgical Society.
In 2015 he spent six months at the Microneurosurgery and Neuroanatomy Training and Research Laboratory of İstanbul University–Cerrahpaşa, working on the microsurgical anatomy of the brain and the ventricles. In 2015 and 2016 he pursued studies in surgical neuroanatomy as a research fellow with Prof. Albert L. Rhoton at the McKnight Brain Institute of the University of Florida, in the United States. In 2017 he trained in neuro-oncology, awake tumor surgery and functional brain mapping under the direction of Prof. Hugues Duffau at the Gui de Chauliac Hospital of the University of Montpellier.
He completed the four-year course program of the European Association of Neurosurgical Societies (EANS) and passed the EANS board examination.
Between 2018 and 2020 he completed his post-residency compulsory service at the Department of Neurosurgery of Haseki Training and Research Hospital. He has practiced at Koç University Hospital since September 2020. In 2022 he trained in neuroendoscopic surgery at the Pituitary Research Center of Kocaeli University under the coordination of Prof. Savaş Ceylan.
He is the author of 84 articles published in national and international journals and of 17 book chapters. His work has been recognized with five awards, and he has taken part in research projects supported by TÜSEB, Koç University and the Turkish Neurosurgical Society. He was awarded the title of Associate Professor in January 2022.
He is a member of the European Association of Neurosurgical Societies (EANS), the International Rhoton Society, the Turkish Neurosurgical Society, the Turkish Neuro-Oncology Society and the Turkish Epilepsy Society. He has served on the board of the Turkish Neurosurgical Society since 2023. He is married and has two children.
In his approach to patients he gives precedence to accurate indication, safe surgery and individualized treatment options directed at preserving and improving quality of life.
