Our laboratory is interested in understanding how mucosal immune responses are coordinated to maintain homeostasis and respond to microbial infection, barrier disruption, or alterations in commensal microbial diversity — with an emphasis on how these molecular decisions are balanced within the context of host fitness and organ physiology.
The Arpaia Lab is part of the Department of Microbiology & Immunology, in the Vagelos College of Physicians and Surgeons at Columbia University Irving Medical Center. As a member of the Graduate School of Arts and Sciences of Columbia University, our Department offers a Graduate Training Program in Microbiology, Immunology and Infection.
