Dr Jian-Yang Li is a research scientist at the Planetary Science
Institute, Arizona, USA. His interest in Ceres started during his
PhD research when he produced the then-highest resolution maps of
Ceres from Hubble Space Telescope images. These maps revealed a
remarkably uniform surface and suggested the uniqueness of Ceres
among asteroids. After obtaining his PhD in Astronomy from the
University of Maryland, College Park, Maryland, USA in 2005, he was
involved in the Dawn mission as an affiliate, participating
scientist, and co-investigator. He was also involved in a number of
small bodies exploration missions such as Deep Impact,
Stardust-NExT, EPOXI, OSIRIS-REx, and DART.
