We are interested in understanding how the gut communicates with the brain... 

To that end, we are conducting the first open-label trial of probiotics in young children for the treatment of anxiety and abdominal pain.


This treatment will help us understand how people respond to stressful situations not only affective and physiologically, but also at the bacterial level. This project is accepting students who are interested in conducting independent studies or practicums during the summer. Students will be able to help in a variety of research tasks such as running psychosocial paradigms, as well as collecting self-report and physiological data. Other tasks include data management, handling specimens, and foster a warm environment for study participants. If interested, please e-mail the study lead, Samuel Marsan, at
