He earned B.Sc. from the Presidency College in 1942 and M.Sc. in 1944 from Science College campus of Calcutta University and he joined Indian Association for the Cultivation of Science (IACS) in 1945 as a research scholar. In 1952, he took a research job with the Indian Association for the Cultivation of Science (IACS), but to his frustration was required to work on the properties of metals rather than general relativity. Despite these adverse pressures, he was able to derive and publish the equation which is now named for him a few years later. Raychaudhuri equation is a key ingredient in the proofs of the Penrose–Hawking singularity theorems.
