SPECIALIZZAZIONI
Sono nata ad Adana il 22.08.1980. Ho completato le scuole elementari e medie ad Adana. Nel 1998 ho fatto il mio primo passo verso la professione dei miei sogni, iscrivendomi alla Facoltà di Medicina dell'Università di Çukurova, che era la mia prima scelta. Ho completato la Facoltà di Medicina dell'Università di Çukurova nel 2004. Mi sono iscritta al reparto di ostetricia e ginecologia dell'Ospedale di Formazione e Ricerca Numune ad Adana, che era la mia prima scelta, entrando tra i primi dieci in Turchia tra coloro che hanno scelto il reparto di ginecologia e ostetricia all'esame TUS.
Ho scelto l'Ospedale di Formazione e Ricerca Numune di Adana come prima scelta, comprendendo che più casi vengono trattati nei reparti chirurgici, maggiore sarà la competenza professionale. Infatti, l'Ospedale di Formazione e Ricerca Numune di Adana è uno degli ospedali dove si eseguono più interventi chirurgici in Turchia. Durante i 5 anni di residenza ho eseguito migliaia di interventi chirurgici e parti.
Ho completato la specializzazione in ginecologia e ostetricia nel 2009, successivamente sono stata assegnata alla maternità di Adana, che è anche uno degli ospedali con il maggior numero di parti in Turchia. Nel periodo dal 2009 al 2012 ho svolto il servizio obbligatorio presso la maternità di Adana, eseguendo numerosi casi.
Dopo aver completato il servizio obbligatorio, ho iniziato a lavorare presso la clinica di ostetricia e ginecologia dell'Università di Medipol a Istanbul. Ho continuato una formazione intensiva nel campo delle applicazioni accademiche e mediche. Ho condotto numerose ricerche e esperimenti scientifici sia a livello nazionale che internazionale.
Ho lavorato specialmente nei campi della gravidanza, aborto spontaneo, parto, estetica genitale, ginecologia e gravidanze a rischio, infertilità e fecondazione in vitro. Ho completato i programmi di certificazione delle tecnologie riproduttive assistite del Ministero della Salute sia in ginecologia e ostetricia che nelle applicazioni di laboratorio della fecondazione in vitro.
Nel 2018 ho lavorato presso la clinica di ostetricia e ginecologia dell'ospedale "Memorial Şişli" a Istanbul, nel reparto di fecondazione in vitro e trattamento dell'infertilità.
Dopo aver ottenuto il titolo di docente presso l'Università Medipol nel 2018, ho condotto programmi di tirocinio in ginecologia e ostetricia come docente per gli studenti della Facoltà di Medicina dell'Università Medipol.
Ho articoli e ricerche sperimentali pubblicati in molte riviste scientifiche sia in patria che all'estero. Lavorando presso l'Università Medipol per 5 anni (2017-2022), ho aperto la mia clinica e attualmente offro prestazioni ai pazienti nella mia clinica a Istanbul.
Le mie passioni più grandi a livello sociale sono la pittura, il cinema e i viaggi. Inoltre, pratico il pilates reformer e sono una fan del basket, perché anche i miei figli giocano. Sono madre di due bambini, Rüzgar e Nehir.

I graduated from Ankara University, Faculty of Medicine, in 1984. After compulsory service, I traveled abroad (UK, Saudi Arabia, Greece and Russia) for a many years to study and work in the fields of gynecology and infertility. In 1997, I received my specialist training from Kartal Training and Research Hospital. Following my training, I worked at Kartal SSK hospital. In 2001, I went to Tel Aviv University in Israel and received training In Vitro Fertilization and reproductive endocrinology. After returning to Turkey, I opened my own in vitro fertilization center ( IVF Center). Following the closure of the hospital in which my IVF center was located due to economic reasons, I started practicing private medicine. A while after that, I started working as the manager of The Gynecological Oncology and IVF Center in Bodrum Acibadem Hospital. Then, I returned to Istanbul, and continued my work in private hospitals as a specialist in gynecological oncology and IVF.
Throughout my long years of experience I did over 15.000 IVF trails.
