Communication, PHD

Location(s): West Lafayette


About the Program


Communication studies at Purdue University celebrate a long and distinguished history, having offered masters degrees since 1947 and granted doctoral degrees since 1948. As the field has developed over time, Purdue faculty and graduate students have been at the forefront leading those advancements in discovery, learning, and engagement.

The Department’s award-winning faculty are some of the most prolific scholars in the field and have made major theoretical, methodological and applied contributions to the study of Communication. Indeed, the Chronicle of Higher Education’s “Top Research University Faculty Scholar Productivity Index” for 2007 placed Purdue at No. 2 in the nation.

Communication graduate students are award-winning as well and have received national and international recognition for their research and teaching. Many graduate students have solo-authored or published collaboratively and are actively involved in individual research projects or research teams. Graduate students have also received university and national recognition for excellence in teaching. They work with faculty as teaching assistants and teach courses on their own. Many students also work on grant-funded research with faculty.

The Communications graduate program is organized along six instructional units:

  • Health and Risk Communication
  • Interpersonal Communication
  • Media, Technology, and Society
  • Organizational Communication
  • Political Communication
  • Public Relations

Program Requirements


90 Credits Required

(30 credits from a Master’s may be applied.)

Required Courses (42-72 credits)


A minimum of 42 hours of coursework beyond the Master’s degree is required for the PhD degree (not including a minimum of 18 hours of dissertation work). 

Major Area (18-48 credits)


COM 60411 or an equivalent graduate level research methodology course is required.

Health and Risk Communication

Issues of health have become increasingly critical and complex, generating the need for individuals who can communicate effectively about health. The health communication program seeks to fulfill this growing need for trained health communicators by exposing students to the theory, research, and practice of health communication.

In addition to courses offered within the Lamb School, students are encouraged to supplement their study of health communication with courses offered in the areas of Human Development and Family Studies, Consumer Science, Health and Kinesiology, Health Sciences, Nursing, Pharmacy, Psychology, Sociology, and/or Women’s, Gender, and Sexuality Studies.

Interpersonal Communication

Scholarship in interpersonal communication focuses on the study of fundamental processes that occur in all social interactions (message production and interpretation). Additionally, such scholarship explores the codes (verbal and nonverbal) through which everyday interactions are accomplished and the functions that people pursue in these interactions such as persuading, informing, and providing support. Scholars investigate how communication shapes, and is shaped by, human relationships, including friendships, romances, families, and work relationships.

Students benefit from faculty connections with many interdisciplinary programs on campus. Students are encouraged to supplement their studies with courses offered in Anthropology, Human Development and Family Studies, Linguistics, Psychology, and Sociology and to explore opportunities in allied research centers, such as Center on Aging & the LifecourseCenter for Education and Research in Information SecurityCenter for Families, and the Military Family Research Institute.

Media, Technology, and Society

Graduate work in Media, Technology, and Society covers research on media and technological processes, their consequences, and the role that mass communication plays in both public and private life. Courses focus on local, national, and global media systems and audiences, as well as emerging information and communication technologies and environments.

MTS faculty members are engaged in various interdisciplinary initiatives, including the Regenstrief Center for Healthcare Engineering, the Center for Education and Research in Information Security and Assurance (CERIAS), the Envision Center for Data Visualization, the Purdue Systems CollaboratoryPurdue Polytechnic Institute, the Purdue Center for the Environment, and the Purdue Policy Research Institute. Students have the opportunity to develop research and professional connections through all of these programs.

Organizational Communication

Organizational communication examines the relationships between communication and organizing through the study of discourse, meanings, symbols, and information flow. Situated in a preeminent engineering, science, and land grant institution of the Big 10, Purdue University Brian Lamb School of Communication’s Organizational Communication program aligns with the pragmatic historical foundations of the Redding Tradition as well as cutting-edge research on global, virtual, as well as cutting-edge research on global, virtual, or online organizations and the influence of national and international policy.

Interdisciplinary connections include: Burton D. Morgan Center for EntrepreneurshipCenter for Education and Research in Information Assurance & SecurityCenter on Aging and the LifecourseDiscovery Learning Research CenterPurdue Policy Research Institute; and Purdue Peace Project. Students are also encouraged to take courses from other disciplines, including Management, Psychological Sciences, Women’s, Gender, and Sexuality Studies, Civil Engineering, Polytechnic, and Interdisciplinary Studies

Public Relations

Purdue’s public relations program doesn’t just focus on what should be done to build and maintain strong relationships between organizations and publics, but why it should be done. The program emphasizes the integration of public relations theory and research into practice to develop an understanding of the interactions between organizations and their publics. Studying public relations prepares students to cultivate and sustain mutually beneficial relationships between organizations of all types and their strategic publics, both as practitioners and researchers.

Minor Area (15-36 credits)


Every student must take a minor in Research Methodology of at least 9 credit hours. In addition, students should another minor (or more) that is not in their major area, with at least 6 credits required for each.

A foreign language may be used to satisfy the Research Methodology requirement only if it will be used in the writing of the dissertation.

Thesis Research (18 credits)
