Position description

The Department of Plant & Microbial Biology at the University of California, Berkeley seeks applications for a Postdoctoral Researcher in the Harmon Lab, in the general area of plant cold tolerance and circadian rhythms.

The Harmon lab investigates circadian clock regulation of environmental responses in panicoid grasses, including sorghum, maize, and foxtail millet. The lab seeks to identify fundamental mechanisms that underpin circadian clock influence over environmental cues by use of genetic, molecular, and genomics approaches.

The position is part of a National Science Foundation Plant Genome Research Program project to investigate the role biological rhythms play in cold tolerance of panacoid grasses. The ultimate goal is identifying where rhythmic regulation can be used to mitigate fitness costs associated with engineering increased cold tolerance of sorghum. The project will employ transcriptomics, metabolomics, and lipidomics to compare the transcriptional and metabolic regulatory modules in cold tolerant foxtail millet and to those in cold sensitive sorghum, with a particular focus on where the circadian clock contributes to tolerance. To establish tools for tolerance engineering, the activity of foxtail millet promoters predicted to be cold responsive and rhythm generating will be tested in engineered sorghum lines. This is a collaborative project with the Roston, Obata, and Schnable labs at University of Nebraska at Lincoln. The incumbent will carry out research to address the goals described above, preferably while mentoring undergraduate students. They will share results through lab meetings and discussions with the PI, and will summarize results in the form of scientific papers. They will work closely with collaborators at University of Nebraska at Lincoln. Postdocs are also expected to take part, as all other lab members, in a limited range of standard lab chores.

The position will contribute to three efforts 1) identification of key rhythmic transcripts and metabolites bypreparation of time course samples for transcriptomic, metabolomic and lipidomic analysis (growing out sorghum plants, time course sampling, lipid analysis sample preparation, coordination with collaborators)and in silico analysis of resultant multi omics data sets (manipulation of large data sets, performing rhythm analyses on large data sets, gene and protein annotation); 2) determine the extent of circadian clock regulation of low temperature tolerance (analyze mutant lines as above); and 3) identify promoter tools for improvement of sorghum cold tolerance (design transgenic constructs, work with contractor to generate transgenic lines, characterize genotype and phenotype of transgenic lines including reporter and
endogenous gene expression.

Basic qualifications (required at time of application)
PhD (or equivalent international degree) or enrolled in a PhD (or equivalent international degree) program.

Additional qualifications (required at time of start)
  • PhD (or equivalent international degree) required by the appointment start date.
  • No more than one year of post-degree research experience by start date.

Preferred qualifications
  • Demonstrated expertise in plant biology, molecular biology, genomics and genetics.
  • Strong publication record in peer reviewed journals showing productivity/
  • Experience in analysis of omics data sets, including scripting in R and Python.
  • Excellent writing and communication skills.
  • Strong interpersonal and teamwork skills.
  • Experience working with sorghum or maize
