  Today's colleges and universities consist of highly complex structures that
dictate interactions between the administration, faculty, and student body.
These structures can play a role in dictating the efficiency of policy enacted
by the administration and determine the effect that curriculum changes in one
department have on other departments. Despite the fact that the features of
these complex structures have a strong impact on the institutions, they remain
by-and-large unknown in many cases. In this paper we study the academic
structure of our home institution of Trinity College in Hartford, CT using the
major and minor patterns between graduating students to build a temporal
multiplex network describing the interactions between different departments.
Using recent network science techniques developed for such temporal networks we
identify the evolving community structures that organize departments'
interactions, as well as quantify the interdisciplinary centrality of each
department. We implement this framework for Trinity College, finding practical
insights and applications, but also present it as a general framework for
colleges and universities to better understand their own structural makeup in
order to better inform academic and administrative policy.
