Biographical Sketch


Professor Magnuson received his B.S. in Biochemistry at the University of Minnesota, and M.S. and Ph.D. degrees in Bacteriology at the University of Idaho, under the guidance of Professor Don L. Crawford. The dissertation research focused on biomass conversion, more specifically the bacterial enzymes of lignocellulose degradation. His research focus changed abruptly upon joining Professor Derek Lovley’s group at the University of Massachusetts as a Postdoctoral Scientist investigating the biochemistry of iron respiration in Geobacter, a versatile and extremely interesting bacterium. That experience led to a Postdoctoral position with Dr. Gill Geesey of Montana State University, where he developed novel new methods for investigating microbe-mineral interactions. Dr. Magnuson joined the Faculty at Idaho State University in 2001, and has developed a suite of collaborative projects with scientists at ISU, Montana State University, Idaho National Laboratory, Utah State University, and NASA Ames Research Center.

The Magnuson Microbiology Group investigates how microbes survive and thrive in exotic environments, using even more exotic substrates. While our work is foundational, we believe that this knowledge will help in developing new technologies and approaches to solve humankinds challenges of clean energy and clean environment. Funding from Department of Energy, National Science Foundation, and NASA have enabled their explorations, and they use research as a teaching and training platform for undergraduate, graduate, and postdoctoral students.
