Doris Löve was born in Kristianstad, Sweden. She studied botany at Lund University from 1937. She married her fellow student and colleague, the Icelander Áskell Löve. She received her PhD in botany in 1944. Together, Áskell and Doris Löve undertook numerous investigations of the chromosome numbers of plants and their use in plant systematics. They published numerous accounts in this field.
In 1962, she was the convener of an influential scientific conference on the North Atlantic Biota and their History  with contributions from a.o. Eric Hultén, Tyge W. Böcher, Hugo Sjörs, John Axel Nannfeldt, Knut Fægri, Bruce C. Heezen and Marie Tharp.
