Berkeley Lab's Climate & Ecosystems Division has an opening for a NGEE-Arctic Vegetation Modeling Postdoctoral Scholar. We seek a postdoctoral scholar to model the impact of climate and disturbance on Arctic shrub distributions and feedbacks to climate change. You will be part of a team at Berkeley Lab working on the NGEE-Arctic project. This project aims to improve predictive understanding of the carbon-rich Arctic system processes and feedbacks to climate. The research goals for you are to project changes in arctic shrub distributions and future shrub expansion in response to climate change and to explore the controls and consequences of these vegetation shifts. The specific objectives for you will include developing representations of dynamic Arctic vegetation for a demographic, trait-enabled dynamic vegetation model called ELM-FATES; testing drivers and representations of vegetation competition and productivity involving nutrient availability and plant hydraulic stress; nitrogen-fixing vegetation; evaluating model representation of current and trending distributions of Arctic vegetation types; and using observations to explore potential controls on rates of shrubification.
You will be part of a team developing mechanistic and testable land models that can be applied across spatial and temporal scales and integrated with Earth System Models. Analyzing terrestrial biosphere responses to warming across the pan-Arctic domain is an important component of the research. We particularly encourage applicants with Arctic modeling experience or other Arctic experience.
What You Will Do:
* Develop and apply new representations of vegetation demography and ecosystem processes and implement them in numerical process-based land models.
* Develop and apply mathematical and/or conceptual models for terrestrial processes across a range of spatial and temporal scales.
* Explore the impact of climate change and disturbance on shrub dynamics, carbon cycling, and plant trait distributions in the Arctic.
* Simulate seedling processes at the site scale using NGEE observations from surveys and experiments.
* Evaluate the extent and drivers of Arctic shrubification.
* Evaluate parameter and structural uncertainty in land models.
* Work creatively, independently, and productively.
* Work as a member of a large multidisciplinary research team.
* Publish peer-reviewed journal articles and present work at scientific conferences.
* Contribute to progress reports and team deliverables.
What Is Required:
* PhD in ecology, earth sciences, or a related field.
* Background in terrestrial ecosystem ecology.
* Strong mathematical skills.
* Experience using land-surface biogeochemical models.
* Computer coding skills to develop numerical representations of terrestrial ecosystem processes suitable for site-level and global scale models.
* Experience in terrestrial ecosystem model development and algorithm coding.
* Experience in application of models to analyze ecosystem processes (e.g. biogeochemistry, plant demography, carbon allocation).
* Experience in dynamic and demographic modeling.
* Experience in improving model prediction using benchmarking tools and uncertainty quantification.
* Ability to carry out uncertainty quantification and calibration activities.
* Excellent written and oral presentation skills.
* Record of timely publications.
* Demonstrated ability to work in teams and independently.
* Arctic modeling experience or other Arctic research experience.
* Ability to handle large data sets.
* Experience with benchmarking and uncertainty quantification.
Required Materials (To be submitted through LBNL recruitment system):
* Curriculum vitae
* Cover letter
* 1-2 of your publications
The posting shall remain open until the position is filled.
* This is a full time, 1 year, postdoctoral appointment with the possibility of renewal for up to three years 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: Lawrence Berkeley National Lab, 1 Cyclotron Road, Berkeley, CA.
Berkeley Lab (LBNL, http://www.lbl.gov/) addresses the world's most urgent scientific challenges by advancing sustainable energy, protecting human health, creating new materials, and revealing the origin and fate of the universe. Founded in 1931, Berkeley Lab's scientific expertise has been recognized with 13 Nobel prizes. The University of California manages Berkeley Lab for the U.S. Department of Energy's Office of Science.
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.
