The Evolutionary Genomics Group at Stellenbosch University has a post-doctoral position available in the Department of Botany and Zoology to investigate the structural organization (architecture) and genomic plasticity of the meiotic genomes of African antelope. Large-scale chromosomal changes such as inversions, translocations, fusions and fissions "reshuffle" genomic segments providing new chromosomal forms on which natural selection can work. Since these new forms are produced in the germ line they can, at least potentially, be fixed in populations thereby providing new heritable allelic variants that are essential for the maintenance of genetic diversity (Heredity 108 (1): 28-36).

There is extensive karyotypic diversity among African antelope where genomic reshuffling is often rapid and many closely related species possess different karyotypes indicating that chromosomal differentiation often occurs during, or shortly after cladogenesis. Our recent data suggest that the number of meiotic DSBs initiated in the early stages of meiosis and final crossover events are influenced by how the genome is organized into chromosomes, and that there is a phylogenetic component in recombination rates (Proc Biol Sci 280(1771):20131945). This appears to be directional, strongly punctuated and subject to selection.

A strong background in one or more the following areas would be advantageous:
· comparative genomics
· molecular systematics
· bioinformatics

The incumbent will work closely with researchers in two other groups: Dr Aurora Ruiz-Herrera (Universitat Autònoma de Barcelona, Spain, and Professor Jiri Rubes (Veterinary Research Institute, Czech Republic) but will be located in the Stellenbosch lab. The appointment is for one year with the possibility of renewal contingent upon satisfactory progress. This position is available immediately.

Expressions of interest should be sent to Terry Robinson ( and should include the names and contact details of 2-3 referees, a full CV and a covering letter that highlights the appropriateness of your expertise and why you are interested in the position.
