  • Laren Becker

    Laren Becker

    Assistant Professor of Medicine (Gastroenterology)

    BioI am a physician-scientist in the Division of Gastroenterology at Stanford University. My clinical and research interest has been in neurogastroenterology. Specifically, my research has been exploring the interplay between immune cells and the enteric nervous system, and evaluating how perturbations of this interaction as a result of aging disrupts gastrointestinal neuromuscular function. Ultimately, my hope is that insights from this research provide novel therapies for treating patients with motility disorders like constipation and irritable bowel syndrome.
