The Energy Geosciences Division at Lawrence Berkeley National Laboratory (LBNL) has an exciting opportunity for a Water Cycle Postdoctoral Scholar with expertise in high performance computer modeling of integrated surface and subsurface hydrologic flow and/or reactive transport in watersheds. Depending on the expertise and interests of the successful applicant, the position will involve either
The development of frameworks to link interoperable and extensible HPC software packages for flow, transport, and reactions in the Critical Zone at scales up to that of the watershed and river basin
Development of an integrated surface-subsurface water flow simulator that includes capabilities for adaptive mesh refinement and embedded boundaries using the Chombo framework, or both.
Ultimately the software will be used to consider climate-induced ecosystem responses across spatiotemporal scales, leading to a scale-adaptive modeling capability for the important terrestrial water and biogeochemical cycles.
What You Will Do:
Develop a coupled software framework linking different processes operating at the watershed scale within the Critical Zone (the Earth's surface and shallow subsurface), including integrated surface and subsurface hydrologic flow, nutrient transport, vegetation and other land surface processes, and biogeochemical reactions.
Develop an integrated surface-subsurface water flow by combining the Richards equation with the 2D diffusive wave equation using the Chombo AMR and EB capabilities.
Collaborate with observational biogeochemists to improve predictive capabilities for water flow and biogeochemical processes.
Identify and develop new research areas and proposals.
Engage as a member of a large, multidisciplinary research team that includes geochemists, hydrologists, and computational scientists.
Author peer-reviewed journal articles and technical reports.
What Is Required:
Ph.D. in computer science, civil or environmental engineering, geochemistry, or hydrology, or equivalent discipline.
Substantial knowledge and experience in modeling hydrologic flow using high performance computers, including parallel simulation and large dataset analysis and manipulation.
Proven knowledge and experience in parallel programming (openMP, MPI) in C/C++ and mixed-language projects.
Ability to identify and develop new research areas and proposals.
Ability to collaborate with a multidisciplinary team of scientists.
Excellent written and oral communications skills and a proven track record of publishing in high-impact journals are also required.
Additional Desired Qualifications:
Knowledge of modeling approaches for multicomponent reactive transport.
The posting shall remain open until the position is filled.
This is a full time, 2 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 3 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.

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.
