In 1928, her work was published in the University of California Publications in Botany In 1953, she became the first president of British Phycological Society. During her 33 years of research in botany she collected over 2,700 species. botany she collected over 2,700 species.

Discovery o Poryphyra o The “purple seaweed” Poryphyra was considered a single life history stage. o Poryphyra. o In 1949, Kathleen Drew Baker discovered the lifecycle of the seaweed Poryphyra. o Conchocelis rosea Poryphyra. o She realized the Conchocelis rosea was part of the life cycle of the Poryphyra. o o Porphyra has a trimorphic life history, with a thallus stage, carposporophyte stage and a filamentous Conchocelis phase (sporophyte stage).
Contribution o Her discovery lead to the establishment of an artificial nori-farming technology in Japan. o She helped the economy of Japan and provided reliable cultivation of Nori seeding. o Nori- (commonly known in Japan) name given to the processed Poryphyra into traditional food. o Before her discovery, the annual production of nori from 1925 to 1957 was 3-5,000 tons. o After her discovery, the annual production of nori from 1958-1980 was 5,000-35,000 tons.
