She was born in 1944. She obtained her doctorate at the end of her studies. In 1969, she was appointed as a
research assistant at the
National Museum of Natural History. Later, within this institution, Cusset was the first to digitize botanical data from the regions covered by her research, between 1985 and 1988. She is partly known for having described two new genera of Podostemaceae, "Djinga" and "Zehnderia", and 18 new species, in addition to renaming 35 others. Her choices in reorganization and renaming subsequently opened new avenues for research. == Legacy ==
