Normally, a graduate student's principal advisor or thesis committee will attempt to solve problems. Problems involving department policies should be addressed to the Graduate Advisor or Chair.  In the case of more serious problems, the Dean of Physical Sciences and other university officials may become involved, but only after attempts at solving the problem within the Department are exhausted.  Students are also welcome and encouraged to bring concerns or issues to the attention of any department staff member who can guide them on the proper course for resolution.
