The COS Council is a small group of undergraduate students who serve as liaisons between the Computer Science Department and the student body. We work closely with department faculty and staff to improve the experience for undergraduates in the department, namely by:


community among concentrators and certificate students


the academic and professional interests of students

communication between students and faculty


Our Mission

Represent the voices of the Computer Science undergraduates to the University in order to enhance the experience of students in the department.
