Department of Plant and Microbial Biology

PhD, Bacteriology, University of Wisconsin Madison, 2003

Research Interests

Microbial physiology, synthetic biology, geomicrobiology; developing strains, tools and techniques for increasing the robustness of using Shewanella for metabolic engineering and downstream applications in bioenergy (microbial fuel cells), bioremediation, and biocatalysis.


In his research, Jeff Gralnick strives to integrate both classical and modern molecular approaches to understand how bacteria influence our planet and how they can be engineered for applications in bioremediation, bioenergy and biocatalysis. His lab uses Shewanella bacteria to research electron shuttling with flavins and synthetic biology in environmental bacteria. Jeff has also explored microbes throughout Minnesota, namely in the Soudan Iron Mine in northern Minnesota and around Lake Itasca, the headwaters of the Mississippi.
