16280 Groussin           Discovered 2000 June 1 by the Lowell Observatory Near-Earth Object Search at the Anderson Mesa Station.
Olivier Groussin (b. 1976), a planetary scientist at the University of Maryland, played a major role in the calibration of the visible-light instruments on the Deep Impact mission, and he also developed models for interpreting the results from the infrared spectrometer.
