After completing his compulsory service, he served as a Doctor Lecturer and Head of Department at Muğla Sıtkı Koçman University Faculty of Medicine, Department of Radiation Oncology from May 2019 to February 2021. During this period, between March and June 2020, he worked as a clinical researcher in the Department of Radiation Oncology at Maastricht University Medical Center–MAASTRO Clinic (Netherlands) on studies related to stereotactic radiotherapy, thoracic radiation therapy-associated lung toxicity, and proton therapy. Between March 2021 and April 2023, he worked at the Radiation Oncology Department of Istinye University Faculty of Medicine and Liv Hospital Ulus Radiation Oncology Clinic, where he received the title of Associate Professor in February 2023. He has been providing services to his patients at Hisar Hospital Intercontinental since May 2023.
Throughout his professional life, he has performed both traditional and advanced radiotherapy practices. Particularly, he is one of the experienced physicians in Turkey in stereotactic radiotherapy and MRI-guided radiotherapy treatments, which are gaining popularity and usage recently. So far, he has successfully completed over 2500 radiotherapy sessions using the MR-Linac device.
Since 2013, he has been a member of the Turkish Radiation Oncology Society (TROD) and since 2015 a member of the European Society for Radiotherapy and Oncology (ESTRO). He has 27 published articles in national and international journals, 31 oral-poster presentations at national and international congresses, and 5 book chapters published by national and international publishers. He has taught undergraduate courses in Period I and Period V at Muğla Sıtkı Koçman University Faculty of Medicine, master’s courses within the ENT Department Specialist training, and Radiation Therapy associate degree courses at Istinye University Health Services Vocational School.
