Manju Ray is an Indian scientist in Molecular Enzymology and Cancer Biochemistry. She has done notable work in the development of anticancer drug and understanding of differentiation process of cells. Her interests cover tumor biochemistry and molecular enzymology.
Ray graduated from the Calcutta University with degrees in M.Sc. in Physiology in 1969 and Ph.D in Biochemistry in 1975. She started her career in the Department of Biochemistry, Indian Association of Cultivation of Science and became a professor. She is an Emeritus Scientist at the Bose Institute of the Council of Scientific and Industrial Research (CSIR). Her research has, over a long span of her career in the department of biochemistry at the Indian Association for the Cultivation of Science (IACS), Jadavpur, in association with a team of scientists and doctor has led to positive development of a drug for cancer treatment.
