A jury found Bishop-Anderson guilty of one count of capital murder just hours after her trial began, WAFF-TV, Huntsville, reported.
The jury of eight men and six women, including two alternates, was sworn in after a brief selection process in an accelerated trial expected to last a day or two, Judge Alan Mann said.
The death penalty had been taken off the table in the case, and Mann sentenced her to life without parole.
Bishop-Anderson pleaded guilty to capital murder and attempted murder Sept. 11, but Alabama state law requires capital murder pleas to still go before a jury.
Bishop-Anderson, 47, is a Harvard-educated biologist and former University of Alabama faculty member who admitted going on a shooting rampage after she was denied tenure at the university.
District Attorney Rob Broussard asked the surviving victims present to stand so the jury could see them. Bishop was seated directly opposite former colleagues and survivors Debra Moriarty, Joseph Leahy and other members of victims' families but did not look at them, The Huntsville Times reported.
