EXECUTIVE PROFILE

I was born in 1969 in Turkey. I became a general practitioner after graduation from GATA medical faculty in 1993 and worked as a general practitioner between 1994 and 1996. I have performed my “Infectious Diseases and Clinical Microbiology” fellowship in GATA Haydarpasa Training Hospital in Istanbul during 1996-2000. I worked as sn infectious diseases specialist in Sivas Hospital in 2000-2003. I became an assistant professor in Gulhane Medical Academy in 2003, and an associate professor in 2006. I worked as the chief of Infectious Diseases and Clinical Microbiology Department in GATA Haydarpasa Hospital in Istanbul between July 2014 and July 2015. I became a Full Professor in June 2015. Subsequently, I worked in the field in several hospitals and currently, I am working for the ministry.
