In our 4th episode, we sit down to have a brief chat with Dr. Barney Geddes, visiting WSU Vancouver from North Dakota St. University; Dr. Geddes studies the intricate dynamics of the nitrogen-fixing Rhizobia and legume plant symbioses. His work is building towards synthetic versions of this symbiosis within non-legumes that could increase crop yield while reducing dependence on chemical nitrogen fertilizer applications. We chat about both his research and development of his specific interests but also learn about his biggest scientific failure, his biggest 'aha' moment, and where he'd most like to travel to.
