Postdoctoral Position in Maize/Rice Protein Biochemistry and Proteomics van Wijk lab, Cornell University, Ithaca, NY, USA. [1]http://cbsu.tc.cornell. edu/vanwijk/ Experienced Plant Protein Biochemist
A postdoctoral position (2-3 years) in Plant Protein Biochemistry and Proteomics in the van Wijk lab is available to contribute to a collaborative project (Cornell, Yale and Iowa Universities) sponsored by the NSF-Genome program. This project concerns a cell-type specific comparative analysis of C3 and C4 leaf development in Rice, Sorghum and Maize.
In leaves of such C4 grasses photosynthetic activities are partitioned between two morphologically and biochemically distinct bundle sheath (BS) and mesophyll (M) cells. The objectives are to compare the quantitative and qualitative patterns of transcripts, proteins, metabolic activities and anatomy at discrete stages and in specific cell types in rice (C3), maize and sorghum (C4), and to develop a model of the regulatory networks governing C4 anatomy and function.
These experimental datasets will be linked by new informatics tools for comparative transcriptional and proteome analysis, to provide the foundation for a systems biology approach to understanding C4 biology. The responsibilities of the postdoc include isolation of subsets of leaf proteomes (e.g. BS strands), protein separation and proteome analysis, as well as biological interpretation of these large scale data sets. Experience in plant protein biochemistry (with a proven track record) and a strong interest in plant metabolism, leaf growth, development and systems biology is required.
Experience with nanoLC-Electrospray tandem Mass Spectrometry (e.g. LTQ, Q-TOF or LTQ-Orbitrap) is beneficial. The postdoc will work closely together with other team members, including mass spectrometry specialists and bioinformaticians. Salary will be commensurate with experience with generous employee benefits according the Cornell Human Resource Office. Review of applications will begin immediately, and continue until the position is filled.
