Fifteen Gynaecologists, doctors, and scientists from India’s leading medical institutions have been recognized in Stanford University’s 2026 list of the world’s top 2% of scientists, according to a database curated by Professor John P.A. Ioannidis in collaboration with the Elsevier Data Repository. The recognition highlights their pioneering research, clinical achievements, and sustained impact in Obstetrics and Reproductive Medicine. The Stanford database provides standardized metrics including citations, h-index, and a composite indicator (c-score), selecting the top 100,000 scientists by c-score or a 2% or above percentile rank in their sub-field.

Dr Neerja Bhatla of AIIMS New Delhi

Dr. Neerja Bhatla, a renowned Indian Gynecologist and Obstetrician, received the Padma Shri in 2025 for her work in women’s healthcare, particularly cervical cancer detection and prevention. She developed resource-based guidelines for cervical cancer screening and HPV vaccination, focusing on low-resource settings over 35 years. Ranked 65,782 in the 2026 Stanford list by composite score excluding self-citations, Dr. Bhatla holds an h-index of 15 with 1,180 citations by end-2025. Her research spans Clinical Medicine, with subfields in Obstetrics and Reproductive Medicine and Oncology and Carcinogenesis. She previously led AIIMS’s Obstetrics and Gynecology department and the Gynaecologic Oncology National Cancer Institute, Jhajjar.

Dr. Bhatla, a past President of the International Federation of Gynaecology and Obstetrics (FIGO), revised FIGO’s cervical cancer staging guidelines in 2018. She continues research on cervical cancer prevention, including HPV epidemiology and affordable testing trials, after retiring from AIIMS. Her work has influenced global health policies and clinical practices in reproductive medicine across diverse healthcare environments.
