Dr. Bibha Chowdhuri (3 July 1913 – 2 June 1991) is one of the most pioneering Indian women in science, renowned for her groundbreaking work in particle physics, cosmic rays, and high-energy physics. She emerged as a leader in experimental physics during a time when few women pursued STEM careers in India.
Born and raised in Kolkata, Bibha was the only woman in her M.Sc. physics batch at the University of Calcutta in 1936 — a remarkable feat in pre-independence India. After graduating, she joined the Bose Institute, where, alongside physicist D. M. Bose, she conducted innovative cosmic ray research using photographic nuclear emulsions — contributing to early evidence of meson phenomena in subatomic physics.
Dr. Chowdhuri went on to earn her Ph.D. at the University of Manchester, focusing on extensive air showers — the cascades of secondary particles created when cosmic rays hit Earth’s atmosphere — under the guidance of Nobel laureate Patrick Blackett. Her doctoral work strengthened India’s footprint in experimental particle detection and cosmic ray physics.
In 1949, she was handpicked by Homi J. Bhabha to become the first woman researcher at the prestigious Tata Institute of Fundamental Research (TIFR) in Bombay, breaking gender barriers in Indian scientific institutions. At TIFR, she led research that helped identify several K-meson states, deepening understanding of subatomic particle interactions.
Throughout her career, Bibha collaborated internationally — from France’s Centre National de la Recherche Scientifique to visiting positions at the University of Michigan — and later contributed to major Indian physics programs like the Kolar Gold Fields (KGF) experiments, key projects in the nation’s high-energy physics history.
Despite her enormous contributions to nuclear and particle physics, Bibha Chowdhuri remained under-recognized during her lifetime. Yet her legacy continues to inspire women scientists, and in recognition of her impact, the International Astronomical Union named a star “Bibha” (HD 86081) in her honor.
