Environmental Molecular Sciences Laboratory (EMSL)

The William R. Wiley Environmental Molecular Sciences Laboratory (EMSL), is a U.S. Department of Energy (DOE) Office of Biological and Environmental Research (BER) user facility. EMSL is the DOE's premier molecular sciences laboratory with state-of-the-art instruments, such as powerful microscopes, spectrometers, and an advanced scientific computing infrastructure. EMSL offers the scientific community a diverse range of unparalleled expertise and advanced instrumentation, and the ability to collaborate with researchers from academia, government labs, and industry. Studying nature at the molecular level provides critical information about the drivers of large-scale environmental functions. The ability to study the processes and interdependencies between proteins and other biological molecules helps researchers understand how microbes and plants affect soils, watersheds, ecosystems, regional climate, and, ultimately, Earth systems.

Environmental Transformations and Interactions Area

The Environmental Transformations and Interactions Area focuses on the mechanistic and predictive understanding of environmental (physiochemical, hydrological, biogeochemical), microbial, plant and ecological processes in above and belowground ecosystems, the atmosphere, and their interfaces. EMSL provides the experimental, computational, and simulation expertise to investigate and model cycling, transformation, and transport of critical nutrients, elements, contaminants, and atmospheric aerosols. Experiment and modeling approaches will accelerate mechanistic understanding of coupled soil-microbe-plant-atmosphere molecular processes and their interdependencies, ultimately informing models of ecosystem processes and land-atmosphere interactions at larger scales.

Functional and Systems Biology Area

The Functional and Systems Biology Area focuses on elucidating and harnessing the biochemical pathways that connect gene functions to complex phenotypic responses through a deep understanding of interactions within cells, among cells in communities, and between cellular membrane surfaces and their environment for microbes (archaea, bacteria, algae), fungi, and plants. This understanding will encompass experimental observations, metabolic reconstruction and modeling, leading to improved strategies for designing plants, fungi, and microbes for biofuels and bio-based products, as well as unraveling the complexities of carbon, nutrient, and elemental cycles within cells and their immediate environment.

Computing, Analytics, and Modeling Science Area

The Computing, Analytics, and Modeling Science Area focuses on using state-of-the-art experimental data to develop a predictive understanding of biological and environmental systems through advanced data analytics, visualization, and computational modeling and simulation. EMSL's cohesive approach to integrating experimental and computational methods advances predictive approaches to biodesign for biofuel and bioproduct production and accelerates research to understand the molecular mechanisms underlying biological and hydro-biogeochemical processes controlling the flux of materials, such as carbon, nutrients, and contaminants, in the environment.

TOUR EMSL

EMSL is one of the 28 DOE Office of Science user facilities. EMSL is housed on the campus of Pacific Northwest National Laboratory in Richland, Washington. DOE’s BER program supports EMSL and several other user facilities facilities, enabling users to conduct research related to the fundamental understanding and prediction of complex biological, Earth, and environmental systems for energy and infrastructure security.
