3 year NSF-supported postdoctoral position is available at University of California San Diego, Department of Scripps Institution of Oceanography, La Jolla, CA, USA to study “Evolution of Left-Right Asymmetry in Chordates using Cephalochordates as a Proxy for the Ancestral Chordate.” A major outstanding question is how left/right (LR) asymmetry evolved. Vertebrates are superficially symmetric, but internal organs are asymmetrically arranged across the left/right (LR) axis. This study aims to elucidate the fundamental genetic mechanisms of LR asymmetry in chordates by comparing two distant amphioxus genera (Branchiostoma and Asymmetron). Pharyngeal structures in larvae of both genera are asymmetrically arrayed, but asymmetries differ between them with gill slits opening on the right in B. floridae and ventrally in A. lucayanum. Applicants with a background in evo/devo and/or developmental mechanisms of amphioxus are preferred. A PhD is required.
Interested applicants please submit a curriculum vitae, names, addresses and e-mail addresses for three references to Dr. Linda Z.
