Woods Hole Oceanographic Institution
Woods Hole, MA U.S.A.
Postdoctoral investigator position available to participate in
NIH-funded research to examine the function of the aryl hydrocarbon
receptor (AHR) signaling pathway (including AHR1, AHR2, and AHR
Repressor) and its role in vertebrate development and in the
developmental toxicity of chlorinated dioxins and related chemicals. The
research will involve a combination of the following approaches: in vivo
promoter analysis and functional knock-down of gene expression in
zebrafish embryos, molecular cloning of AHR pathway genes in zebrafish,
Fugu, and medaka, phylogenetic analysis and comparative genomics, in situ
hybridization, cell transfection, and functional genomic analyses in fish
and in mammalian cells. Results will be interpreted within the context
of the evolutionary relationships among the genes and species under
study. (See representative publications listed below.) Molecular biology
experience is essential. Previous experience in one or more of the
following is desirable: zebrafish developmental biology;
microinjection of fish eggs; transgenic fish technologies; comparative or
functional genomics; in situ hybridization; microscopy; mammalian cell
Start date: As soon as possible, but position will remain open until
filled. One year appointment, possible extension for up to 3 years.
Salary: Starting at ~$47,320 per year, depending on previous experience.
Education required: M.D. or Ph.D. in biochemistry, molecular biology,
toxicology, developmental biology, genomics or related field. Less than
4 years postdoctoral experience.
