Berkeley Lab's Earth & Environmental Sciences Division has an opening for a Analytical Biochemistry Postdoctoral Scholar to work within a five-year project funded by the Department of Energy's Biological and Environmental Research (BER) on cell wall metabolism and physiology of natural and transgenic California poplar trees. The incumbent 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 and photorespiration), and leaf emissions of methanol, acetic acid, and methyl acetate as a function of plant genotypes and environmental variables including temperature and moisture availability. You will help lead laboratory, greenhouse, and field experiments and be based in the new Biochemical Ecology Laboratory within the Climate and Ecosystem Sciences Division at Berkeley lab and will spend time at the Joint BioEnergy laboratory (JBEI), NMR facilities and the Oxford growth chamber facilities at the University of California Berkeley, and participate in specific metabolomics experiments in the Environmental Molecular Sciences Laboratory (EMSL) in Washington State.
What You Will Do:
Help acquire poplar trees of known genotypes from collaborators in Oak Ridge National Laboratory (ORNL) including groups of individuals with altered cell wall methylation and/or acetylation levels and work with a nursery technician to help establish them at the UC Berkeley Oxford Growth Facilities (and at EMSL as relevant).
Participate in instrumentation calibration, maintenance, and preparing and running samples, as well as collecting and processing data on cell wall chemical composition, metabolomics, volatile emissions, plant physiology and hydraulics, and environmental variables.
Work with collaborators at JBEI, UC Berkeley, and EMSL for mass spectrometry based metabolomics analysis of tissue extractions and cell wall chemical analysis using biochemical assays and 2D/3D solution state and solid state nuclear magnetic resonance spectroscopy.
Help develop and demonstrate a novel xylem 13C-solution injection methodology scaled to sap flow and help prepare both a technical and scientific manuscript and patent application for this technology.
Help run and maintain instrumentation for leaf volatile emissions and interface them to plant chambers including thermal desorption gas chromatography-mass spectrometry and proton transfer reaction-mass spectrometry.
Run and maintain a portable photosynthesis system, porometry for stomatal conductance, pressure chambers for leaf water potential, and sap velocity sensors for continuous estimates of whole plant transpiration.
Assist the PI and project collaborators and undergraduate and graduate students during laboratory, greenhouse, and field experiments.
Lead the publication of scientific research results in peer-reviewed international journals and help with project logistics and data archiving, analysis and sharing and project website.
What is Required:
PhD 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 analysis of tissue extractions, and cell wall chemical analysis using biochemical assays and 2D/3D solution state and solid-state nuclear magnetic resonance spectroscopy.
Experience with methods in plant ecophysiology, 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, porometry for stomatal conductance, pressure chambers for leaf water potential, and sap velocity sensors.
Able to be based in Berkeley lab within the Climate and Ecosystem Sciences Division and spend time at the Joint BioEnergy laboratory (JBEI), NMR facilities at UC Berkeley Chemistry and the Oxford growth chamber facilities. In addition, the applicant will be required to be based at EMSL in Washington State to lead poplar metabolomics experiments for up to one year in the event of a successful user facility proposal.
The posting shall remain open until the position is filled.
This is a full time, 1 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 4 years paid postdoctoral experience. Salary for Postdoctoral positions depends on years of experience post-degree.
Full-time, M-F, exempt (monthly paid) from overtime pay.
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 McCone Hall at University of California, Berkeley - 307 McCone Hall, Berkeley 94720-4767.

About Lawrence Berkeley National Laboratory
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.
