Paul Alan Cox is an American ethnobotanist whose scientific research focuses on discovering new medicines by studying patterns of wellness and illness among indigenous peoples.
Early in his academic career he was named a National Science Foundation Presidential Young Investigator by Ronald Reagan, and used the research funds to pursue his interests in mathematical biology and ethnobotany.
[9] He discovered with colleagues Sandra Banack and James Metcalf in cyanobacteria AEG, a hypothesized backbone of peptide nucleic acids in the pre-RNA world early in the earth's history.
Although trained in evolutionary ecology, because of his fluency in Polynesian languages, Cox was encouraged by Harvard Professor Richard Evans Schultes to pursue ethnobotanical studies.
Subsequently, with his colleagues Gordon Cragg, Michael Boyd, and others at the National Cancer Institute, they discovered the anti-HIV/AIDS properties of prostratin found in the bark of the mamala tree of Samoa.
[24] Cox lived with his family in the village of Falealupo on Savai'i island in Samoa where he helped create a covenant with chiefs to protect their lowland rainforest from logging.
