9026 Denevi           Discovered 1988 Sept. 16 by S. J. Bus at Cerro Tololo.
Brett W. Denevi (b. 1980) is a planetary scientist at the Johns Hopkins University Applied Physics Laboratory and an expert in the composition and evolution of asteroid surfaces. She analyzed pitted terrain on Vesta, finding its structure to be consistent with devolatilization of the surface.
