It was while studying for her PhD at the University of Cambridge that Francoise first became interested in Amazonian culture and conservation. She has pursued this interest through her research and teaching career at Cambridge and has always maintained close links with her research partners in Peru. As a co-founder of Yacumamay, Francoise has extended her commitment to support the conservation of traditional knowledge within its original context.

Born in Chazuta in the department of San Martin, Gilber settled in Iquitos after finishing military service. During the early 1970s Gilber trained as a public health worker and continues to serve his community in this way. As the son of a famous plant shaman Gilber learnt about medicinal plants from an early age, this knowledge allied with his role as a local leader has been instrumental in the establishment of the Yacumamay project.
