PhD position
Dissecting the genetic basis of co-selected traits during thermal
adaptation Principal advisors: Neda Barghi and Christian Schlötterer
Institute of Population Genetics, Vetmeduni, Vienna, Austria

Both temperature mean and temperature fluctuations have important roles
in thermal adaptation. Recent studies suggest that adaptation to mean
temperature and fluctuation in temperature are distinct traits but
their genetic basis and distinct effects of these selective pressures,
i.e. constant and fluctuating temperature, on thermal adaptation are
still largely unknown.

This project aims to characterize genomic regions involved in thermal
adaptation and to dissect the genes responsible for adaptation to either
higher mean temperature or fluctuating temperature. This work will take
advantage of 30 replicates of Drosophila simulans evolved for over 100
generations in two temperature regimes (constant 23°C and fluctuating
between 18 and 28°C).

You will have the opportunity to investigate two traits, i.e. adaptation
to mean temperature and fluctuation in temperature, by combining time
series Pool-Seq data, gene expression profiling and phenotypic assays.

Preferred skills
- Background in experimental or computational fields such as
bioinformatics, evolutionary genetics, or experimental
population genetics
- Experience in programming (Python/R)
- Good oral and written communication skills

Why do your PhD with us?
We offer
- 1 month intensive course in population genetics
- Weekly seminar series with internationally renowned experts
in the field
- International and interdisciplinary environment
- Vienna is among the most liveable cities in the world
