Postdoctoral position in
Plant evolutionary ecology
Postdoctoral position on sexual dimorphism and gene expression changes in response to different sex chromosomes in the lab of Dr. Tia-Lynn Ashman, as a part of a collaborative NSF-funded project with Dr. Aaron Liston examining functional and genomic consequences of sex chromosome evolution.
The postdoc will assess consequences of sex chromosome turnover for sexual dimorphism in functional traits, abiotic stress tolerance, species interactions, and gene expression by analyzing reproductive and vegetative QTLs and transcriptomes from several genetic linkage mapped families. The postdoc will ultimately link these to processes driving sex chromosome turnover events as part of the overall project using the octoploid wild strawberry (Fragaria) a model system with young homomorphic ZW sex chromosomes (Tennessen et al. 2018 PLOS Biology https://doi.org/10.1371/journal.pbio.2006062).
Responsibilities include the establishment and characterization of QTL mapping populations, collection and analysis of data for genetic maps, phenotypic, species interaction and gene expression analyses, and the preparation of manuscripts for publication.
Position affords opportunities for training in QTL and gene expression studies and in
undergraduate mentoring, scientific outreach, and the design and implementation of allied projects tailored to the skills and interests of the postdoc.
An ideal candidate is 1) evolutionary-minded with complementary skills, willingness to cross-train and collaborative spirit, 2) has background in evolutionary ecology, population biology or population genomics, plant biology and 3) desire to expand expertise in quantitative genetics, genetic mapping, gene expression, functional ecology or species interactions.
Position is for three years and will be based in the Department of Biological Sciences at the University of Pittsburgh, Pittsburgh, PA. Start date is negotiable, but expected early 2020.
TO APPLY: Please send a CV and a cover letter describing your experience and interests to email@example.com along with the names and contact information for three referees. Review of applications will commence immediately and continue until filled.
