PhD position on amphibian sex chromosome evolution

A three-year-PhD position in evolutionary biology is available at the
Leibniz-Institute of Freshwater Ecology and Inland Fisheries (IGB)
in Berlin, funded by the German Research Foundation (DFG). The PhD
student will be affiliated with the Humboldt University of Berlin,
and working with Matthias Stoeck on the evolution of sex chromosomes
of amphibians. We use next generation sequencing (NGS) genome data to
develop molecular genotyping and sequence markers that will be applied
in sibship and population genetics analyses to study the evolution
of homomorphic sex chromosomes. Applications to endocrine disruptive
substances of none-model anuran species are planned.

Requirements: We are looking for an enthusiastic, empirical and
“organismal” PhD student with a master or diploma in (evolutionary)
biology, experience with molecular wet lab approaches (PCR, genotyping,
cloning), population genetics analyses, ideally experience with
bioinformatics analyses of NGS data, and experience to work with live
amphibians or fish.

Salary will be paid according to the TVöD for a 50% position. In keeping
with the IGB's policy regarding gender equity, female applicants are
particularly encouraged; disabled people with identical qualifications
will be favored.

Please, send a motivation letter including research interests and
experience, CV, and the email-addresses of at least two referees via
email to:
by August 10, 2012.
