Tal Korem works at the intersection of computational biology and medicine to develop microbiome-based therapeutics and diagnostics.

By using analytical approaches and tools like machine learning, network inference and metabolic modeling, he aims to understand microbial growth, activity, and metabolic production in humans.

Core to Korem’s research is understanding the mechanisms of host-microbiome interactions. However, these mechanisms typically involve more than a single microbial component. They are ecosystem-level phenomena, the result of numerous interactions between trillions of microbes in the ecosystem, and between them, the host, and its environment. A system with so many delicate moving parts will behave differently when put in an animal model or a test tube and perturbations can produce unintended and unexpected effects. Korem’s group takes a different approach to host-microbiome interactions: instead studying the components, they model the system as a whole, using data from real patients.
