In this exciting role, you will work within a project funded by the Department of Energy's Biological and Environmental Research (BER) on cell wall metabolism and physiology of natural genetic variants of California poplar trees. The postdoc will help explore the integration of cell wall acetyl and methyl ester metabolism with plant hydraulics (stomatal conductance, transpiration, water potential, etc), primary carbon and energy metabolism (photosynthesis, photorespiration, respiration, and fermentation), and leaf emissions of methanol, acetic acid, and isoprene as a function of plant genotypes and environmental variables including temperature and moisture availability.
What You Will Do:
Lead project laboratory, greenhouse, and field experiments in collaboration with the PI, project collaborators, and students.
Participate in instrumentation installation, calibration, and maintenance. Help run instrumentation for leaf and branch gas exchange including thermal desorption gas chromatography-mass spectrometry and proton transfer reaction-mass spectrometry for volatiles, a portable photosynthesis system, an isotope spectrometer for CO2 and O2, pressure chambers for leaf water potential, and sap velocity sensors.
Design and execute experiments, and collect and process data on cell wall chemical composition, metabolomics, transcriptomics, volatile emissions, plant physiology and hydraulics, and environmental variables.
Work with collaborators at JGI and EMSL for mass spectrometry-based metabolomics analysis of tissue extractions and cell wall chemical analysis using biochemical assays and solution state NMR.
Study poplar trees of known genotype at the UC Davis drought field site with collaborators from ORNL including regular travel from Berkeley to Davis during the growing season.
Help maintain poplar plants for experimental work at the UC Berkeley Oxford tract greenhouse as well as 40 trees growing in the field site.
Lead project logistics and data archiving, analysis and sharing and contribute to the project website.
Lead the preparation of technical methods and scientific manuscripts and potentially a patent application for developed technologies.
Regularly present research updates during weekly group meetings and prepare and present posters and oral presentations at international conferences in the biological, atmospheric, and geological sciences.
What is Required:
Ph.D. in related science field with sufficient technical research experience with demonstrated scientific accomplishments including publication of research results in peer-reviewed journals.
Experience with advanced analytical instrumentation including, for example, mass spectrometry-based volatile emissions, metabolomics and transcriptomics analysis of tissue extractions, biochemical assays, and leaf gas exchange systems.
Experience with methods in plant ecophysiology such as gas exchange, volatile organic compounds, and biochemistry methods applied to greenhouse/growth chamber studies including thermal desorption gas chromatography-mass spectrometry, proton transfer reaction-mass spectrometry, portable photosynthesis systems, 13C-labeling methodologies in plant sciences.
Able to be based in Berkeley lab in the Biochemical Ecology laboratory within the Climate and Ecosystem Sciences Division at Berkeley lab and spend time at the Joint BioEnergy laboratory (JBEI), the UC Berkeley greenhouse and field facilities, and regularly travel to UC Davis to conduct field research during the growing season.
This position will remain open until filled.
This is a full-time, one-year, postdoctoral appointment with the possibility of renewal based upon satisfactory job performance, continuing availability of funds and ongoing operational needs. You must have less than four years of paid postdoctoral experience.
Salary for Postdoctoral positions depends on years of experience post-degree.
This position is represented by a union for collective bargaining purposes.
Salary will be predetermined based on postdoctoral step rates.
This position may be subject to a background check. Any convictions will be evaluated to determine if they directly relate to the responsibilities and requirements of the position. Having a conviction history will not automatically disqualify an applicant from being considered for employment.
Work will be primarily performed at Lawrence Berkeley National Lab, 1 Cyclotron Road, Berkeley, CA.

In the world of science, Lawrence Berkeley National Laboratory (Berkeley Lab) is synonymous with excellence. Thirteen scientists associated with Berkeley Lab have won the Nobel Prize. Fifty-seven Lab scientists are members of the National Academy of Sciences (NAS), one of the highest honors for a scientist in the United States. Thirteen of our scientists have won the National Medal of Science, our nation's highest award for lifetime achievement in fields of scientific research. Eighteen of our engineers have been elected to the National Academy of Engineering, and three of our scientists have been elected into the Institute of Medicine. In addition, Berkeley Lab has trained thousands of university science and engineering students who are advancing technological innovations across the nation and around the world. Berkeley Lab is a member of the national laboratory system supported by the U.S. Department of Energy through its Office of Science. It is managed by the University of California (UC) and is charged with conducting unclassified research across a wide range of scientific disciplines. Located on a 200-acre site in the hills above the UC Berkeley campus that offers spectacular... views of the San Francisco Bay, Berkeley Lab employs approximately 4,200 scientists, engineers, support staff and students. Its budget for 2011 is $735 million, with an additional $101 million in funding from the American Recovery and Reinvestment Act, for a total of $836 million. A recent study estimates the Laboratory's overall economic impact through direct, indirect and induced spending on the nine counties that make up the San Francisco Bay Area to be nearly $700 million annually. The Lab was also responsible for creating 5,600 jobs locally and 12,000 nationally. The overall economic impact on the national economy is estimated at $1.6 billion a year. Technologies developed at Berkeley Lab have generated billions of dollars in revenues, and thousands of jobs. Savings as a result of Berkeley Lab developments in lighting and windows, and other energy-efficient technologies, have also been in the billions of dollars. Berkeley Lab was founded in 1931 by Ernest Orlando Lawrence, a UC Berkeley physicist who won the 1939 Nobel Prize in physics for his invention of the cyclotron, a circular particle accelerator that opened the door to high-energy physics. It was Lawrence's belief that scientific research is best done through teams of individuals with different fields of expertise, working together. His teamwork concept is a Berkeley Lab legacy that continues today.
