Early life and education

DeLong was born in

Indiana University in Bloomington with Norman Pace, where he surveyed communities of picoplankton via DNA sequencing
.

Work

Energy gathering mechanism in marine bacteria via Proteorhodopsin.

With Pace and his group at Indiana University, DeLong developed a method that can be used to identify single cells phylogenetically through the use of

oligonucleotides that are complementary to 16S
rRNA sequences of specific phylogenetic groups. The use of multiple probes with different fluorescent dyes allows for the identification of different cell types in the same field.

DeLong subsequently expanded upon this work and applied

microbial culture
.

After receiving an independent study award in 1989, DeLong spent some time at the

hydrothermal vents
, and similar places. This changed the general view of the scientific community on the role of archaea in the biosphere and opened up new possibilities in applied potential of such microbial assemblages.

In the years following, DeLong's work took him to the Monterey Bay Aquarium Research Institute and it is during his time there that he made a crucial discovery in the understanding of the Earth's carbon and energy cycles. A team of microbiologists led by DeLong discovered a gene in several species of bacteria[4] responsible for production of the protein rhodopsin, previously unheard of in the domain Bacteria. These proteins found in the cell membranes are capable of converting light energy to biochemical energy due to a change in configuration of the rhodopsin molecule as sunlight strikes it, causing the pumping of a proton from inside out and a subsequent inflow that generates the energy.[5] In 2004, DeLong moved to the Massachusetts Institute of Technology, where he worked on developing gene expression studies targeting microbial communities in the wild. At MIT, his collaborations with CMORE and Monterey Bay Aquarium Research Institute colleagues, he discovered of highly synchronized microbial populations having oscillating patterns of gene expression[6] across many species. In 2014, DeLong relocated to the University of Hawaii, where he serves as co-director for the Center for Microbial Oceanography: Research and Education, C-MORE[7] and the Simons Collaboration on Ocean Processes and Ecology, SCOPE.[8]
