Timothy Dinan

Timothy Dinan coined the term psychobiotics and has established how gut microbial metabolites influence brain function through vagal and humoral pathways, with emerging implications for cancer-related depression, cognitive decline, and chemotherapy-induced neurotoxicity. His clinical studies demonstrate that specific probiotic interventions can modulate stress responses and immune function in cancer patients. He leads translational research on the microbiome-gut-brain axis in psycho-oncology.
