Christoph Thaiss
Assistant Professor of Pathology
Current Research and Scholarly InterestsThe Thaiss Lab investigates how gut-brain interactions influence health and disease. By studying microbiome-host communication, the lab explores how microbial signals impact immune function, metabolism, and neurological health. Using multi-omic technologies and computational models, they aim to uncover mechanisms underlying inflammation, neurological disorders, and metabolic diseases. Their research supports the development of personalized therapies targeting the gut-brain axis.
