Guillaume Bay

I am a microbial ecologist in Kirsten Hofmockel’s lab with broad interests in ecosystem processes, microbial communities, plant-microbe symbiotic relationships, and nutrient cycling.
More specifically, my research focuses on the long-term consequences of organic amendments and crop-system diversification on soil microbial community composition, as well as the metabolically active populations involved in carbon and nitrogen transformations.
By combining microcosm experiments with high-throughput sequencing methods, I aim to provide valuable knowledge about how microbial diversity regulates nutrient cycling, allowing us to develop sustainable management strategies that maintain crop yields whilst guarding ecological integrity.
