I work at Eskişehir Osmangazi University Faculty of Medicine. My special interest is head and neck surgery.

After a career of over 30 years in the field of otolaryngology, when I reach the title Asso. Prof. Dr. in which I combined rigorous medical practice with teaching and scientific activity I extend my level of research. My deep interest in pediatric rhinology and ENT has developed over time, in response to the growing needs of patients and the specific challenges of these subspecialties. Rhinology, through the complexity of nasosinusal pathologies and continuous technological evolution, has motivated me to constantly follow the latest discoveries in the field. On the other hand, pediatric ENT represents a special mission for me, in which science is intertwined with empathy and responsibility towards the most vulnerable patients – children. I also actively participate in nasal allergy research, especially in pediatric patients.
