Tadashi Takeuchi

Postdoctoral Scholar, Microbiology and Immunology

BioDr. Tadashi Takeuchi is a physician-scientist and postdoctoral scholar in the Sonnenburg Laboratory at Stanford University. He earned his MD and PhD from Keio University, Japan, and completed his residency training in internal medicine and his diabetology fellowship at St. Luke’s International Hospital, Japan. Throughout his training, he has studied host–microbe interactions in the intestine with a focus on the influence of dietary nutrients. His PhD studies with Hiroshi Ohno, MD, PhD, at RIKEN IMS, Japan, focused on the impact of dietary short-chain fatty acids on intestinal immunity, culminating in a first-author publication in Nature. Leveraging his expertise in diabetology, he also investigated host–microbe interactions in metabolic disease during his PhD, ranging from mechanistic studies to human multi-omics, resulting in multiple first-author publications in Nature and Cell Metabolism. At Stanford, Dr. Takeuchi integrates clinical training, immunology, computational multi-omics, and bacterial genetics to develop strategies that establish robust, diet-guided colonization by therapeutic commensals. His long-term goal is to translate these insights into microbiome-based interventions for human diseases. His work has been recognized with the NIH K99/R00 Pathway to Independent Award and Stanford School of Medicine Dean’s Postdoctoral Fellowship, among multiple early-career awards.
