science & technology notes for 9 February 2026

Kamal Jayasing Ranadive was a pioneering Indian biomedical researcher whose work transformed cancer biology in India. She is best known for establishing India’s first Tissue Culture Research Laboratory in the 1960s at the Indian Cancer Research Centre, Mumbai. Her scientific focus on cancer, tumour viruses, hormones and immunology laid a strong experimental foundation for modern oncology research. She also co-founded the Indian Women Scientists’ Association, encouraging women’s participation in science. Her career combined laboratory excellence, public health research and national scientific leadership.

Kamal Ranadive Biography

Kamal Ranadive was born on 8 November 1917 in Pune to Dinkar Dattatreya Samarath and Shantabai Samarath. His father was a biologist at Fergusson College, She completed her BSc with distinction in Botany and Zoology in 1934 and earned an MSc in cytogenetics in 1943 from the Agriculture College, Pune. After marrying mathematician J. T. Ranadive in 1939, she moved to Bombay. She pursued doctoral research at the University of Bombay under pathologist V. R. Khanolkar, receiving her PhD in 1949. She later trained in tissue culture techniques at Johns Hopkins University with George Gey. She passed away on 11 April 2001 at the age of 83.
