Christina Kellogg
Applying molecular techniques and microbiology methods to study marine microbes, particularly the microbial ecology of tropical and deep-sea corals.
Biography
Dr. Kellogg grew up on a charter boat in the U.S. Virgin Islands with the Caribbean Sea as her backyard, so it was no wonder she pursued a career in marine biology. Chris is an environmental microbiologist who applies molecular techniques to characterize and identify microbial communities. After receiving her bachelors of science degree in biology from Georgetown University, Chris pursued a Ph.D. in marine microbiology from the University of South Florida, working on the genetic diversity of environmental viruses. This was followed by postdoctoral research on an NIH-funded fellowship to identify novel drug targets in pathogenic fungi and an internship at Human Genome Sciences. Dr. Kellogg joined the U.S. Geological Survey as a Mendenhall Fellow, characterizing the microbial communities in aerosolized African desert dust, beach sediments, seagrass beds and coral reefs. Currently, she leads an environmental microbiology laboratory at the U.S. Geological Survey specializing in coral microbial ecology. Her research on tropical corals has taken her to the Florida Keys, Caribbean, Hawaii, and American Samoa, leading her friends to say that she specializes in ‘resort microbiology.’ Chris has been working in deepwater coral ecosystems since 2004 and considers herself extremely lucky to have had the privilege of visiting them personally using the Delta and Johnson-Sea-Link submersibles. She has authored more than 30 peer-reviewed papers as well as a number of book chapters and has given invited keynote talks on both her aerosol microbiology and deep-sea coral microbial work. Chris served as a judge for the $2 million dollar Wendy Schmidt Ocean Health XPRIZE competition in 2015 and is currently judging the $7 million dollar Shell Ocean Discovery XPRIZE. She was elected to the Council Policy Committee (de facto executive board) of the American Society for Microbiology (2012–2016), playing an active role in revamping the communication and governance structures of the organization. Chris is active in shaping the direction of microbiome research in the U.S., having represented DOI on the Federal Microbiome Interagency Working Group and being a part of the National Microbiome Data Collaborative.

Microbial Processes on Reefs
The microbial community on coral reefs is generally underappreciated given the ubiquity, abundance, complexity, and formative role these prokaryotes serve in the metabolic and chemical processes on reefs. We use microbiological and metagenomic techniques to decipher the roles the microbial community are playing in processes such as coral disease, submarine groundwater discharge, calcification...
Coral Microbial Ecology
The coral microbial ecology group has an active research program identifying and characterizing the microbial associates of both tropical and cold-water (deep-sea) corals and their surrounding habitat. Current projects focus on coral disease dynamics, bacterial diversity, and using metagenomics to elucidate the functional roles of coral microbes.
DISCOVRE - Diversity, Systematics and Connectivity of Vulnerable Reef Ecosystems Project
This project uses amplicon sequencing, and functional microarrays to examine the microbiomes of several deep-sea coral species, with priority given to species that are also of interest to the population genetics group: Desmophyllum dianthus, Lophelia pertusa, Enallopsammiasp. and Acanthogorgia sp. The project also uses metagenomics to survey benthic habitats including coral mounds, cold seeps...
Coral Reef Ecosystem Studies (CREST)
The specific objectives of this project are to identify and describe the processes that are important in determining rates of coral-reef construction. How quickly the skeletons of calcifying organisms accumulate to form massive barrier-reef structure is determined by processes of both construction (how fast organisms grow and reproduce) and destruction (how fast reefs break down by mechanical...

Coral Disease
We investigated coral disease processes and causes by characterizing microbial communities in diseased and healthy representatives of selected coral species both temporally and spatially by employing microarray technology. We tested the diagnostic potential of coral fluorescence for identifying disease-induced physiological stress.

Microbiomes of stony and soft deep-sea corals share rare core bacteria
Background: Numerous studies have shown that bacteria form stable associations with host corals and have focused on identifying conserved “core microbiomes” of bacterial associates inferred to be serving key roles in the coral holobiont. Because studies tend to focus on only stony corals (order Scleractinia) or soft corals (order Alcyonacea), it...
Kellogg, Christina A. MICROBIAL ASSOCIATIONS OF FOUR SPECIES OF ALGAL SYMBIONT-BEARING5 FORAMINIFERS FROM THE FLORIDA REEF TRACT, USA
While microbiome research is a rapidly expanding field of study, relatively little is known of the microbiomes associ- ated with Foraminifera. This preliminary study investigated microbes associated with four species of Foraminifera, repre- senting two taxonomic orders, which host three kinds of al- gal endosymbionts. A major objective was to...
Martin, Makenna M.; Kellogg, Christina A.; Hallock, Pamela Stability of temperate coral Astrangia poculata microbiome is reflected across different sequencing methodologies

Brendan; Buster, Noreen A.; Phillips, Ryan M.; Frometa, Janessy Chapter 12. Canyons microbiology studies
Off the eastern coast of the United States, several deep canyons cut through the continental shelf, acting like funnels to move sediment from the shelf out to the deep seafloor. Exposed rock outcrops and ledges along the walls of these canyons provide important habitat for deepsea corals and sponges. Although a few scientific expeditions have...

USGS microbiome research
Microbiomes are the communities of microorganisms (for example, bacteria, viruses, and fungi) that live on, in, and around people, plants, animals, soil, water, and the atmosphere. Microbiomes are active in the functioning of diverse ecosystems, for instance, by influencing water quality, nutrient acquisition and stress tolerance in plants, and...

Over the last decade, publications on deep-sea corals have tripled. Most attention has been paid to Lophelia pertusa, a globally distributed scleractinian coral that creates critical three-dimensional habitat in the deep ocean. The bacterial community associated with L. pertusa has been previously described by a number of studies at sites in the...

Kellogg, Christina A.; Goldsmith, Dawn Bacterial community diversity of the deep-sea octocoral Paramuricea placomus
Compared to tropical corals, much less is known about deep-sea coral biology and ecology. Although the microbial communities of some deep-sea corals have been described, this is the first study to characterize the bacterial community associated with the deep-sea octocoral, Paramuricea placomus. Samples from five colonies of P. placomus were...
Kellogg, Christina A.; Ross, Steve W.; Brooke, Sandra D. Coral-associated bacterial diversity is conserved across two deep-sea Anthothela species
Cold-water corals, similar to tropical corals, contain diverse and complex microbial assemblages. These bacteria provide essential biological functions within coral holobionts, facilitating increased nutrient utilization and production of antimicrobial compounds. To date, few cold-water octocoral species have been analyzed to explore the diversity...
