PNNL, Washington University to lead multimillion-dollar 'grand challenges' at DOE national user facility
RICHLAND, Wash., and ST. LOUIS -- The W.R. Wiley Environmental Molecular Science Laboratory (EMSL) at the Department of Energy's Pacific Northwest National Laboratory will embark on two "grand challenges"-- innovative, multidisciplinary projects--to explore scientific enigmas in microbiology and biogeochemistry.
One, led by Washington University biology professor Himadri Pakrasi and PNNL laboratory fellow David Koppenaal, will investigate the biology of membrane proteins in cyanobacteria, important microorganisms involved photosynthesis in the world's oceans. The other, led by PNNL laboratory fellows and chief scientists John Zachara and Jim Fredrickson, is probing the fundamental question of how subsurface metal-reducing bacteria interact with and transfer electrons to the mineral surfaces on which they live.
More than two dozen researchers from 16 institutions will participate in the three- to- five-year studies, with a PNNL investment of $2 million a year for each grand challenge, or around $10 million for the life of the projects.
Investigators anticipate that the grand challenges will yield new information on issues ranging from how energy and nutrient transport occurs between microbes and their environment, to how microorganisms influence Earth's soil and water chemistry, with potential applications that include groundwater remediation, carbon sequestration, and energy generation.
EMSL's unique and broad-ranging experimental and computational facilities are central to the approach for the projects.
"EMSL is already one of Department of Energy's most successful national user facilities," said Dr. Raymond L. Orbach, Director of the Department of Energy's Office of Science, "so it is a fitting place to attempt such ambitious grand challenges, where we can pair large groups of our most talented scientists with our most sophisticated analytical tools to look at very specific and vexing scientific problems. We are hopeful that this approach will become a model for collaborative research at EMSL and other DOE facilities."
"We are bringing together international expertise to advance an area of science in ways that haven't been possible before," said Allison Campbell, EMSL director. "A combination of world-class minds, methods and capabilities uniquely positions PNNL and EMSL to deliver answers to the grand challenge questions these teams are addressing."
The William R. Wiley Environmental Molecular Sciences Laboratory (www.emsl.pnl.gov) is located on the PNNL campus. Since its inception in 1997, the 200,000-square-foot facility has played host to more than 5,500 visiting scientists, professors and other individuals who requested use of the facility's resources through a peer-review proposal process. These individuals--commonly referred to as "users"--come to EMSL from academia, other research and development laboratories and industry.
