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.

USGS Role in DEEP SEARCH: Deep Sea Exploration to Advance Research on Coral, Canyon, and Cold-seep Habitats
USGS scientists are collaborating with multiple agencies to provide the esssential foundation for understanding these deep-sea environments.
DISCOVRE: Diversity, Systematics and Connectivity of Vulnerable Reef Ecosystems
DISCOVRE (DIversity, Systematics and COnnectivity of Vulnerable Reef Ecosystems) is an integrated, multidisciplinary, international effort investigating the unique and fragile deep-sea coral environments from the microscopic level to the ecosystem level.
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...
Black-band disease in the Florida Keys
Photos of corals affected by black-band disease in the Florida Keys.
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.

Identifying mangrove-coral habitats in the Florida Keys
Coral reefs are degrading due to many synergistic stressors. Recently there have been a number of global reports of corals occupying mangrove habitats that provide a supportive environment or refugium for corals, sheltering them by reducing stressors such as oxidative light stress and low pH. This study used satellite imagery and manual ground-...

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...

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...
