The Network Science PhD program at Northeastern University is a pioneering interdisciplinary program that provides the tools and concepts aimed at understanding the structure and dynamics of networks arising from the interplay of human behavior, socio-technical infrastructures, information diffusion and biological agents.
The PhD in Network Science is an interdisciplinary program supported jointly by the Bouvé College of Health Sciences, D’Amore-McKim School of Business, College of Arts, Media and Design, College of Science, College of Social Sciences and Humanities, and Khoury College of Computer Sciences.
Our interdisciplinary program provides the conceptual and mathematical tools needed to describe and predict networks in an ever-evolving field. You’ll learn a range of network-based approaches, and will become proficient in relational (graph-based), mathematical, and algorithmic techniques, as well as fundamental network theories that can be used to explain mechanisms and processes of networks across domains—in physical, technological, informational, and social systems.
As the only Network Science program based in the U.S., our curriculum provides a scholarly experience that is truly one of a kind. The program fosters intellectual and quantitative agility, enabling you to combine theoretically-driven inquiries with data collection and analytic tools and theories—while also understanding when, and in what contexts, particular techniques are appropriate and meaningful.
Admitted students typically receive financial support in the form of a Graduate Assistantship for 5 years while in good standing in the program. This support typically includes a stipend, tuition remission, and health insurance. Assistantships are provided for the first five academic years, plus the first summer. Continuation of your Assistantship is contingent upon fulfilling all academic and graduate assistantship requirements and may be facilitated through your pursuit of external funding sources, such as fellowships or grants. Conditions relating to PhD Student funding can be found here.
Tuition Remission
Student support typically includes a tuition waiver for coursework pertaining to studies.
Graduate Assistantships
Stipends are provided through Graduate Assistantships. The responsibilities required for Assistantships vary, but typically come in the form of Fellowships, Research Assistantships or Teaching Assistantships. Assistantships are offered with the expectation that the student devotes 20 hours per week to their assistantship duties. Students are admitted into the program with a faculty advisor. Student’s assistantship duties are assigned and performed under the supervision of their faculty advisor.
The annual (including the summer) stipend rate at the Network Science Institute for 2025-2026 will be approximately $43,050. Students are typically paid on a twice-monthly basis.
Research Assistantships (RA)
Support is primarily maintained through research assistantships (RA), for which students are expected to devote 20 hours per week to research assigned through the student’s faculty advisor. RA positions give students the opportunity to participate in research projects as members of a research team. Frequently, this work leads to the students' doctoral thesis projects. Students should expect to spend additional time conducting research in support of their academic studies, such as coursework and activities connected to their dissertation.
Teaching Assistantships (TA)
Graduate students holding teaching assistant appointments must register as full-time resident students and are charged full tuition during the period of appointment. The TA appointment comprises a monthly stipend as well as a tuition scholarship which is credited directly to the student’s account. Teaching Assistants are compensated on the basis of the time devoted to teaching activities. A 100% graduate TA appointment typically includes payment of full tuition for the period of the appointment. Partial appointments (for effort less than 100%) are also possible, and are frequently used to supplement outside fellowships, scholarships, or research assistantships. Students who receive financial support from multiple resources must do so in accordance with department and university guidelines. A 100% teaching assistantship requires no more than 20 hours of effort per week. Northeastern recognizes that graduate students may spend additional time conducting research in support of their academic studies, such as coursework and activities connected to the dissertation.
Other Financial Support
There are also funding opportunities available through external sources where the funds are provided directly to the PhD student rather than through Northeastern University. External doctoral fellowships typically offer stipends comparable to the NU stipend, and some awards offer additional travel or equipment funds. These awards are competitive and rare, though Network Science students have had success with them in the past. If a student receives an extramural award, the external funds will be applied towards stipend and tuition/fees, and the program and/or advisor will supplement as needed to ensure students receive at least the standard support outlined in the admissions letter.
Occasionally, students have a need for supplemental financial support. Information on financial aid loans can be found here.
Health Insurance
All students in the NS PhD program receive health insurance and tuition remission. While Northeastern University covers the cost of the individual graduate student health insurance plan (NUSHP) for its fellowship students and graduate assistantships, you will be required to pay all other university-issued fees (including student fees, roughly $130 per semester, the University Health and Counseling Service fee, estimated at $225 per year, and an additional one-time fee of approximately $375 for international students). Additional information on the student health plan can be found here.
