Complex Networks & Systems Ph.D. Requirements

The complex networks & systems track of the Ph.D. in Informatics includes a focused core of informatics course work, seminars in complex systems, and a strong faculty-supervised research component. When you arrive, you will be assigned a temporary supervisor to help develop your course of study and identify research opportunities before you commit to a dissertation topic and advisor. Independent studies and research rotations, supervised by a faculty member, are an excellent way to investigate new areas of inquiry or deepen your knowledge of a specific subject. Students in this track will also participate in research and events in the outstanding wider community of the Indiana University Network Science Intsitute, with over 150 faculty members who participate in network science and complex systems research and who can serve in interdisciplinary Ph.D. advisory committees.

We also recommend consulting the School of Informatics, Computing, and Engineering Bulletin 2018-2019 (use the tabs on the left) and the University Graduate School Bulletin 2017-2018 (use the tabs at the top and left) for more detailed information about these requirements.


A student must successfully complete ninety (90) credit hours of graduate-level course work. The specific track requirements are listed below.

Informatics Core Requirements (6 cr.)

Complex Systems & Networks Core Requirements (6 cr.)

Seminar Requirement (6 cr.)

Research Rotation Requirement (6 cr.)

A student must complete two rotations of I790. A third rotation will not count for course credit.

Theory and Methodology Requirement (12 cr.)

These courses must be appropriate for a Ph.D. in Informatics.

Minor (6-15 cr.)

A student must complete an internal or external minor approved by the University Graduate School and the School. If a student selects an individualized minor, prior to taking courses, the University Graduate School must approve the proposed minor course list. There is no typical minor; however, students in the Complex Systems & Networks track often pursue a minor in Biology, Computer Science, or Statistics.

Electives (12-30 cr.)

A student must have all electives approved by the student's advisor and the Director of Informatics Graduate Studies prior to enrolling in the course.

Thesis Reading and Research (minimum of 21 cr. and a maximum of 30 cr.)
