Born in 1987 in Seyhan, Adana, he completed all levels of his early education in Adana before earning his Veterinary Medicine degree from Selçuk University in 2011. After serving as a Control and Hygiene officer at Kuleli Military High School during his 2012 military service, he began his professional career as a Veterinarian at the Karaisalı District Agriculture Directorate in Adana. Later that same year, he transferred to the Elbeyli District Agriculture Directorate in Kilis province.

In 2014, he pursued doctoral studies in Veterinary Microbiology at Selçuk University's Health Sciences Institute, completing his PhD in 2021. From 2017 to 2022, he specialized in vaccine development and diagnostics at the Brucella Vaccines Production and Reference Diagnostic Laboratory within the Pendik Veterinary Control Institute Directorate. Currently, he serves as an Assistant Professor in the Department of Microbiology at Van Yuzuncu Yil University's Faculty of Veterinary Medicine, a position he has held since 2022.
