Self-introduction
The discipline of obstetrics and gynecology encompasses four major subspecialties: gynecologic oncology, perinatology, reproductive medicine, and women's healthcare/ My primary focus lies in gynecologic oncology, within which I actively advance the implementation of robotic surgery, digital health technologies, and patient-centered care. In addition, I place strong emphasis on education initiatives designed to ensure that trainees and colleagues are empowered to excel within their respective areas of specialization.
