Dr. Barney Geddes gained a PhD from the University of Manitoba, Canada where he studied the rhizobium-legume symbiosis with the goal of improving rhizobium inoculums for agriculture. His current research focuses on novel strategies to engineer nitrogen fixation in cereal crops. It is his ambition is to use science to contribute to the improvement of agriculture and the global food supply in an environmentally sustainable manner.
Geddes is integrating novel synthetic biology techniques that have been developed in model systems with current understandings of the genetics and physiology of agriculturally important organisms to engineer improvements in agricultural systems. This focuses, specifically, on the use of plant-colonizing bacteria as chassis to engineer nitrogen fixation in cereal crops.
