Roger began his career as a medical entomologist for the Nigerian Ministry of Health (1951-1958), then worked for the Commonwealth Institute of Entomology (1959-1972) before joining the Natural History Museum. He started as head of the Hymenoptera section, then moved to Diptera as head of section before being promoted to Senior Principal Scientific Officer and spending his last years purely on research. He retired in 1990 but remained as a Scientific Associate until 2016.
His contributions to dipterology include biosystematics of Simuliidae and Tachinidae but also of other calyptrate families such as the Muscidae, Rhinophoridae and Calliphoridae. His works include several large monographs published in the Bulletin of the British Museum (Natural History) such as the taxonomic conspectuses of Oriental and Australasian tachinids. He was editor-in-chief of the Afrotropical Diptera Catalogue and contributed chapters to the Afrotropical, Australasian and Oriental regional catalogues, which are still widely in use by the scientific community today, and is author of the cornerstone book on simuliids, 'The Natural History of Blackflies'. He was also a biogeographer and a member of the management committee for the International Trust for Zoological Nomenclature. |
