Katrina Edwards

Katrina Edwards died on October 26, 2014 at the age of 46. Edwards is survived by her parents, her siblings, and her three children.

Edwards was elected a fellow of the American Academy of Microbiology in 2010 and the American Association for the Advancement of Science in 2011. In 2012, she became the third woman to receive one of the highest honors for those working in ocean science, the Royal Society of Canada's A.G. Huntsman Award for Excellence in Marine Science.

While at Woods Hole Oceanographic Institution, Edwards was an associate scientist in geochemistry and marine chemistry. In 2006, she began working at the University of Southern California (USC). There she was a professor in the environmental studies, earth sciences, and biological sciences departments and became a mentor for many students and postdoctoral researchers. In 2009, she helped established the Center for Dark Energy Biosphere Investigations (C-DEBI) at USC. Creation of the technology center was done in partnership with USC, national laboratories, and several major research universities and was supported by the National Science Foundation (NSF) with a $29 million grant. Since then, the Deep Carbon Observatory is also continuing to organize collaborative work on biological activity in the deep subsurface.

Edwards authored over 100 published papers, contributed to and edited several microbiology textbooks, served as the associate editor of American Mineralogist, and served on the editorial boards of Environmental Microbiology, Geobiology and Geomicrobiology journals. Her 2000 paper, "An Archaeal Iron-oxidizing Extreme Acidophile Important in Acid Mine Drainage" featured as the cover story in the journal Science. Edwards also published a blog on Scientific American's website, relating the experiences of her team so members of the public could follow the events as they occurred during a research expedition in the Mid-Atlantic Ocean.

In 1996 Edwards left her work at the airport to attend the University of Wisconsin, Madison where she studied geochemistry, mineralogy, microbiology, oceanography, molecular biology and ecology. There she earned a master's in geology with emphasis on isotope geochemistry and in 1999 she earned the first Ph.D. in geomicrobiology awarded by the university. It was also at UW-Madison she met her future husband. In 1999 Edwards moved to Massachusetts to join Woods Hole Oceanographic Institute. There she established a geomicrobiology lab, which focused on the microbial transformation and degradation of solid Earth materials, specifically rocks, minerals, and organic matter.

Katrina Jane Edwards (15 March 1968 - 26 October 2014) was a pioneering geomicrobiologist known for her studies of organisms living below the ocean floor, specifically exploring the interactions between the microbes and their geological surroundings, and how global processes were influenced by these interactions. She spearheaded the Center for Dark Energy Biosphere Investigation (C-DEBI) project at the University of Southern California, which is ongoing. Edwards also helped organize the deep Biosphere research community by heading the Fe-Oxidizing Microbial Observatory Project on Loihi Seamount, and serving on several program steering committees involving ocean drilling. Edwards taught at the Woods Hole Oceanographic Institute (WHOI) and later became a professor at the University of Southern California.

Katrina Edwards was born the third of five children in March 15, 1968 in Columbus, Ohio, to Sandra and Timothy Edwards. At Columbus Alternative High School Katrina completed her secondary education, and pursued an early career at the Delaware Municipal Airport in general airport operations and later as a chief flight instructor. While continuing her work at the airport, Edwards attended Ohio State University to pursue an undergraduate degree in geology. In 1994, she received her bachelor's degree with honors.
