Biographical Sketch |
|
| Katrina Edwards is a professor of biological sciences and Earth sciences in USC College. She is also the director of the National Science Foundation supported Center for Dark Energy Biosphere Investigations in Los Angeles. Team members along with several other major research institutions are drilling holes in the ocean floor in three locations under the Atlantic ocean--the North Pond, Juan de Fuca and South Pacific Gyre--in order to study how life thrives in sediments and rock below the bottom of the ocean. Her research interests include geomicrobiology and microbial life at or below the sea floor, and the interaction of microbes and rock. The cornerstone of Professor Edwards' lab research is in the development of a mechanistic understanding of the microbial processes and controls on rock, mineral and organic matter transformations, and the establishment of means to delineate their influences. | |
