Research Activities

My main research interest is in development of human gonads and pathogenesis of germ cell disorders, with focus on premalignant lesions, which are associated with gonadal dysgenesis and DSD. The aim of the ongoing studies is to understand why the incidence of germ cells cancer and male infertility have been increasing and to identify possible environmental factors as well as early markers of germ cell transformation.
