Christopher William Marshall

Argonne National Laboratory
United States of America


Christopher William Marshall is a Director’s Postdoctoral Fellow collaborating with Dr. Jack Gilbert and Dr. Ken Kemner on many aspects of applied and environmental microbiology. My background is in thermophilic and mesophilic extracellular electron transfer, anaerobic environmental microbiology, and bioelectrochemical systems. I am currently working on the commercial applications and environmental importance of extracellular electron transfer by microbes to and from insoluble electron acceptors and donors. Recently, my coworkers and I have developed electrosynthetic microbiomes generating high yields of fixed carbon products. I am now utilizing metagenomic and metatranscriptomic datasets in order to better understand this bioelectrochemical system and other microbial communities.
