Research interests
I am fascinated by how metabolic dependencies emerge, evolve, and shape microbial community structure. With a background in biopolymers and anaerobic mixed-culture fermentations, I initially investigated how strong selective pressures can be used to steer microbial communities toward desired product formation. This experience led me to focus more fundamentally on the ecology and evolution of metabolite cross-feeding, and how these dependencies shape microbial community assembly and spatial organization,
potentially contributing to the emergence of multicellularity. I address these questions through controlled bioreactor experiments, experimental evolution in synthetic co-cultures and mathematical modeling.
