PhD Dissertation Committees
As codified in the Graduate Studies Bulletin:

The committee for the final examination for the PhD degree is appointed by the University dean of graduate studies on the advice of the appropriate associate dean of graduate studies. The committee shall consist of:

At least two current full-time tenure-track members with the rank of assistant professor or higher who hold their primary appointments in the department offering the degree program, or are among the core faculty defined for an interdisciplinary PhD program, in the role of “inside members.” The dissertation advisor or supervisor may or may not hold a primary appointment in the department offering the candidate’s degree program but is considered to be inside that department or program for the purpose of committee membership. The advisor must be present for the examination.
