Education and career Lewis graduated in 1973 with a B.Sc. from the University of London. He eventually became the head of the legume section at the Royal Botanic Gardens, Kew, which he joined in 1974. In his research on the legume family he has contributed to the description of 58 species and 11 genera. He has also contributed to several taxonomic revisions, especially for the genus Caesalpinia. In 1994 he received a Ph.D. from the University of St. Andrews. His doctoral dissertation, supervised by Peter Edward Gibbs, is entitled Systematic studies in neotropical 'Caesalpinia L.' (Leguminosae: Caesalpinioideae), including a revision of the 'Poincianella-Erythrostemon group' .

Lewis has collected thousands of botanical specimens and has done botanical "fieldwork in Brazil, Cuba, Argentina, Ecuador, Central America, Mexico and Madagascar". During his career at the Royal Botanic Gardens, Kew, his research has focused on "systematics, phylogenetics, biogeography, diversity and comparative biology of neotropical (mainly South American) Leguminosae, especially Caesalpinioideae (particularly Caesalpinia) and Mimosoideae. Floristic studies focus on the drylands and wet tropics of Brazil and the Andes of Ecuador, including monographic work on the large genus Caesalpinia."
