An NIH-funded postdoctoral position is available in the Sergei Sokol laboratory in the Department of Cell, Developmental and Regenerative Biology, Icahn School of Medicine at Mount Sinai, New York, to study Wnt signaling and cell polarity during early vertebrate development using Xenopus embryos and mammalian stem/progenitor cells. We are especially interested in cell shape and behavior during neural tissue closure and the links between cell polarity and cell fate specification in the skin and the neural crest. See the description of our interests at http://research.mssm.edu/sokol/Sokol_lab/. Preference will be given to highly motivated applicants with strong background in molecular and cellular biology, who published a first-author paper as a result of their graduate work. Interested candidates may send their CV, list of publications and three references to Dr. Sergei Sokol (email@example.com).
