Molecular dissection of symbiosis function in insect-bacterial associations

Our goal is to determine the role of individual genes, specifically bacterial genes horizontally transferred to the insect genome, in mediating symbiosis function in plant sap-feeding insects.  We will test the specific hypothesis (based on preliminary evidence) that these genes function in the two essential symbiosis functions – mediating nutrient transfer between the bacteria and insect host, and regulating bacterial populations.  The research is made possible by recent and ongoing advances in genetic tools (RNAi, CRISPR), omics technologies and metabolic modeling for these symbioses.  Promising genes will be taken forward as candidate targets for novel strategies to control insect pests that absolutely require the bacterial symbiosis. This position is ideally suited to researchers with strong molecular expertise and an interest in host-microbe interactions. Prior experience of working with insects is an advantage.

This is a 12-month appointment, renewable contingent on available work, performance and funding

Qualifications: This position is available to applicants with a PhD in a biological discipline and with a proven track record of effective research output.

To apply: Informal inquiries are welcome, please contact Angela Douglas at Candidates should submit a short cover letter, curriculum vitae, contact information for three references, research statement, and a statement of contribution to diversity, equity, and inclusion via the website .To ensure full consideration, all materials should be received by April 30, 2019; however, applications will be accepted until the position is filled. Competitive salaries commensurate with experience and skills will be offered, as well as generous benefits.
