PROJECT OVERVIEW: We are using a genome-wide association study (GWAS) in combination with linked-read whole-genome resequencing in 30 males and 30 females to test for and identify the genetic basis sex determination in sea lamprey. Sex determination mechanisms in fishes are highly variable, ranging from genotypic (GSD) to environmental (ESD) sex determination. Male-biased sex ratios under conditions of high population density or slow growth have led to suggestions of ESD in lampreys, but there is no conclusive evidence in lampreys of ESD, and no fish species with exclusively ESD are known. Understanding the genetic basis of sex determination in lampreys is important given their phylogenetic position as one of only two surviving groups of jawless vertebrates. Furthermore, the sea lamprey is a significant pest in the Laurentian Great Lakes and genetic manipulation of sex determination could be a powerful tool for control. The Principal Investigators on the project are Drs. Margaret Docker and Colin Garroway (Department of Biological Sciences, University of Manitoba) and Dr. Alison Wright (Department of Animal and Plant Sciences, University of Sheffield).
JOB DESCRIPTION: The primary task of this position will be to test for a genetic basis for sex determination in the sea lamprey. However, the PDF will also have the opportunity to develop and pursue his or her own research questions within the context of sea lamprey evolutionary genomics.
  • To undertake research on the genomics of sex determination in sea lamprey. To contribute significantly to experimental design, data interpretation and statistical analysis.
  • To trial new techniques and assay systems as required and keep abreast of the research literature relevant to the project.
  • Disseminate research through publications in peer reviewed journals.
  • To attend and contribute to research seminars, departmental meetings and international conferences.
  • Carry out administrative roles as required, e.g. organising physical or remote meetings with collaborators, arranging travel to consortium meetings.
  • Perform professional activities such as refereeing papers, editing journals, refereeing research grants, external examining, organising conferences, committee membership and involvement with professional bodies on accreditation.
  • PhD in evolutionary biology, computational biology, or genetics or successful PhD viva at commencement of contract.
  • Proven ability to process and analyse next-generation sequencing data. Experience with Chromium 10X technology is desired but not essential.
  • Proficiency with analysis software and programming languages, as well as ability to write or adapt scripts and pipelines for in silico genetic analysis.
  • Ability to work both collaboratively and independently
  • Well-developed leadership, management and influencing skills
