Formerly an instructor at the University of Besançon, from 1905 to 1914 he conducted a series of geological surveys in the Sahara (later day nations of Mali, Mauritania and Niger). His interests included Quaternary deposits, the formation of sand dunes, processes of aeolian erosion, et al. In the Taoudeni basin, he investigated ancient volcanoes, and south of Agadez, he found the presence of dinosaur bones. In the Zinder region, he made a discovery of Lower Cretaceous rocks being overlain by Upper Cretaceous successions. His geological collections are housed at the Muséum national d'histoire naturelle in Paris.

The botanical species Pennisetum chudeaui Trab. Maire is named in his honor.
