Research interests

My research focuses on the prevalence and molecular typing of Trichomonas vaginalis, a flagellated protozoon colonizing the mucosal epithelium of human urogenital tract and the causative agent of trichomonosis, the most common non-viral sexually transmitted disease (STD) and Mycoplasma hominis, which is an opportunistic human pathogen, a common commensal bacterium of the human female genital tract with the ability to cause genital and neo-natal infections and systematic infections in immunocompromised patients.
