About the PNAS Member Editor
Name DeLong, Edward F.
Location University of Hawaii at Manoa
Primary Field Environmental Sciences and Ecology
Secondary Field Evolutionary Biology
 Election Citation
DeLong applies genomic technologies to dissect complex microbial assemblages. He developed methods for phylogenetic identification, functional characterization, and quantitation of bacterial species, as well as correlating such measurements with environmental parameters. Delong's research has changed marine microbial ecology.
 Research Interests
DeLong's scientific interests address central questions in oceanography and microbiology, with a focus on microbial genomics, biogeochemistry, and microbial ecology, and evolution. Understanding the emergent properties of microbes in their natural environmental settings, from genomes to biomes, has remained a central goal throughout his career. A large part of DeLong's efforts has been devoted to the study of microbes and microbial processes in the ocean, combining field-based approaches and genomic technologies. Development and application of genomic, biochemical and metabolic approaches to study marine microbial communities and processes has been a longstanding, central area of interest for DeLong?s lab. His work has ranged from temperate, to tropical, to polar environments, studying microbial processes from surface waters to the deep-sea. His research accomplishments include the discovery of rhodopsin-based phototrophy in bacteria, the demonstration of the abundance and widespread distribution of planktonic marine Archaea, and recognition of specific lineages of Archaea in the anaerobic oxidation of methane. DeLong currently is coupling high resolution, oceanographic field surveys with advanced genomic technologies, to map the diversity, variability of marine microbial communities in four dimensions in situ, and interpreting those dynamics in the context of global biogeochemical cycles. His current interests also focus on the nature of marine viruses and viral-like particles, and the structural and functional differences of particle-attached microbial communities from surface waters to the deep ocean, and their roles in the global carbon cycle.
