Departmental Liaisons to the IRB (DLI) serve as a resource point for faculty, students, staff regarding the IRB processes.  Anyone who has a question about protocol concepts, content and submission can contact a DLI in their (or closely related) discipline for assistance and direction.

Note that DLIs are not IRB members. As such they cannot officially vote on the IRB. Nor can they officially determine on the behalf of the Committee or the PI whether a protocol or protocol concept will (or is likely to be) exempt from review. Only the IRB can make that determination based on a submitted protocol that requests "exempt from review" status.
