Christina Kellogg, Ph.D.
I am an environmental microbiologist that uses molecular techniques and microbiology methods to study marine microbes, particularly the microbial ecology of tropical and deep-sea corals.
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 the Coral Microbial Ecology Laboratory at the U.S. Geological Survey, studying the microbiomes and environments of tropical and cold-water corals.
Dr. Kellogg is active in shaping the direction of microbiome research in the U.S., having represented the Department of Interior (DOI) on the Federal Microbiome Interagency Working Group, the National Microbiome Data Collaborative, and serving as Subject Matter Expert to the White House Office of Science and Technology Policy rollout of the National Microbiome Initiative in 2016.

African dust carries microbes across the ocean: are they affecting human and ecosystem health?
Atmospheric transport of dust from northwest Africa to the western Atlantic Ocean region may be responsible for a number of environmental hazards, including the demise of Caribbean corals; red tides; amphibian diseases; increased occurrence of asthma in humans; and oxygen depletion (eutrophication) in estuaries. Studies of satellite images suggest that hundreds of millions of tons of dust are tranAuthorsChristina A. Kellogg, Dale W. GriffinAtmospheric microbiology in the northern Caribbean during African dust events
Between July 2000 and August 2001 forty-three air samples were collected in the northern Caribbean: Twenty-six in the US Virgin Islands, and 17 samples aboard ship during two 1-week cruises. Samples were collected during African dust events and non-dust conditions and screened for the presence of culturable bacteria and fungi. A total of 3,652 liters of air were collected during non-dust conditionAuthorsDale W. Griffin, C.A. Kellogg, V.H. Garrison, J.T. Lisle, T.C. Borden, E.A.

Aims: A method for the rapid extraction of fungal DNA from small quantities of tissue in a batch-processing format was investigated. Methods and Results: Tissue (< 3.0 mg) was scraped from freshly-grown fungal isolates. The tissue was suspended in buffer AP1 and subjected to seven rounds of freeze/thaw using a crushed dry ice/ethanol bath and a boiling water bath. After a 30 min boiling step, theAuthorsDale W.

Movement of soil particles in atmospheres is a normal planetary process. Images of Martian dust devils (wind-spouts) and dust storms captured by NASA's Pathfinder have demonstrated the significant role that storm activity plays in creating the red atmospheric haze of Mars. On Earth, desert soils moving in the atmosphere are responsible for the orange hues in brilliant sunrises and sunsets. In seveAuthorsDale W. Griffin, Christina A. Kellogg, Eugene A. Shinn - News
