“Neoproterozoic Earth System and the Rise of Biological Complexity” is an interdisciplinary project directed by Ricardo Trindade at the Instituto de Astronomia, Geofisica e Ciências Atmosféricas (IAG-USP). To examine how changes in ocean redox, nutrients and the evolution of life affected the physiology, ecology and developmental behavior of several groups of metazoans. We are recruiting a postdoctoral researcher with experience in physiology, cell biology, developmental biology, evolutionary biology, astrobiology, or bioinformatics.
Objectives of the project include:
(1) To study the tolerance of modern metazoans (e.g. sponges, cnidarians, acoels, platyhelminthes, nematodes, and tunicates) to Neoproterozoic environmental conditions and oxygen levels.
(2) To search for conserved metabolic pathways in species adapted to distinct oxygen levels. Using a comparative genomics approach, the postdoc will search for ancestral vs. derived gene pathways involved in oxygen metabolism.
(3) To test how oxygen variations drive the evolution of novel phenotypes in artificial selection experiments in C. elegans, a model animal with extensive understanding of the genetic, cellular, and developmental processes.
Provide a letter of interest, CV, and contact information of three potential referees until May 15th to Federico Brown (firstname.lastname@example.org), André Morandini (email@example.com) or Marcio R. Custódio (firstname.lastname@example.org). Start date is any time after August 2018.
