You must find at least one faculty sponsor to support you and help you shape your IC. Your primary sponsor must be a full-time professor with a rank of Assistant/Associate/Full Teaching Professor or Assistant/Associate/Professors; research professors and emeriti professors are also eligible if they currently teach an undergraduate course. Primary sponsors cannot be visiting or adjunct professors, lecturers, clinical professors, or professors of the practice; this is not because they aren't experts but because the regular faculty do not need to renew their teaching contracts annually. It can also be helpful to have multiple faculty sponsors if you are drawing heavily from two somewhat disparate fields, and you find the sole expertise of one formal advisor doesn’t quite meet the needs of your IC.
To find a sponsor, we recommend considering professors you've taken a class from, checking http://vivo.brown.edu to see which professors are conducting research in the field(s) you are interested in, and attending their office hours. Professors are often excited to talk to potential ICers because their work is innovative and unique! The IC Faculty Sponsor Info Sheet provides more information about the faculty sponsor role.
