He is known for the ''“Krori-Barua Solution”'' 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
