Kamalendu Deb Krori (born 21 January 1930) is an Indian theoretical physicist and the former Principal of Cotton College. ^[1]

He pioneered research on general relativity in the North Eastern region of India and guided 16 scholars for their Ph.D. degrees. ^{[2] [3]} He has co-authored almost 150 peer-reviewed research papers in International Journals. He is known for the “Krori-Barua Solution” ^{[4] [5]} a general relativistic solution for a singularity free charged fluid sphere (1975); the pertinent paper has more than 150 citations. In 1982, Krori along with two students showed why the elusive fundamental particles neutrinos, originally believed to be mass-less like the photons, must possess some finite rest mass in order to be consistent with Einstein's general theory of relativity.

In 1998, the Japanese Super-Kamiokande experiment confirmed that neutrinos indeed possess tiny masses by confirming existence of neutrino oscillations by which neutrinos change their flavours during their long cosmic journeys.

Education and career

Krori received a BSc degree from Karimganj College and M.Sc from Calcutta University ^[6] in 1953.

Krori joined Karimganj College and then Cotton College as a lecturer. ^[6] He became a professor at St. Anthony's College, Shillong. ^[6] After holding many teaching positions, he earned Ph.D. degree by virtue of independent research in theoretical physics from Jadavpur University, Kolkata, in 1971. He joined Cotton College, Guwahati, in north-east India, as a lecturer in physics. There he started research on the general theory of relativity. Later he became a full professor and headed the Department of Physics. He became the Principal of the institute in 1987 and retired in 1991.
