He has done extensive analysis of asteroid lightcurves to find pole directions and shapes for more than 25 objects, as well as studies of phase curves which suggest the existence of both rough and smooth surfaces among the asteroids. As one of the first to apply speckle interferometry to these bodies, he developed many theoretical contributions to the analysis of speckle data and produced the first speckle images showing features on the surface of an asteroid, namely, that of (4) Vesta. His enthusiasm for studies of asteroids, comets and meteors has made him a pleasurable colleague for collaborative efforts. Citation provided by Donald R. Davis at the request of the discoverer.
