You are cordially invited to participate in the ninth meeting on Rat Genomics & Models, which will be held at Cold Spring Harbor Laboratory. The meeting will begin with dinner and the first session on the evening of Wednesday, December 9, and will conclude with lunch on Saturday, December 12, 2015. We are looking forward to a broad-based meeting, and abstracts are welcomed on all scientific topics related to rat genetics, genomics and physiology. The format of the meeting will include six oral sessions consisting of invited and short talks, limited to approximately 15 minutes, principally on unpublished work. Oral presentations will be selected by the organizers from the submitted abstracts. The other submitted abstracts will be presented in poster session(s). As is usual at Cold Spring Harbor meetings, all abstracts of both poster and platform sessions will be published in an abstract book given to all the participants.
