Walden University

What you'll study

The programme combines advanced coursework in computing and information science with sustained, original research leading to a doctoral dissertation. Core study areas typically include research design and methods for computing, advanced algorithms and data structures, data mining and machine learning, information systems design, cybersecurity principles and governance, and human–computer interaction. Students also study specialised topics through elective modules such as cloud and distributed systems, big data engineering, applied artificial intelligence, software engineering, and information policy and ethics.

Study progresses from instructor-led, online doctoral seminars and advanced coursework into comprehensive examinations and a multi-stage dissertation process. The dissertation sequence emphasises proposal development, research execution, manuscript preparation and publication. Throughout the programme, students engage in peer review, faculty supervision and research practicum activities designed to build methodological rigour and scholarly communication skills.

Entry requirements

Applicants are normally expected to hold a relevant master’s degree from an accredited institution or demonstrate equivalent graduate-level coursework and professional experience in computing or information sciences. Typical application materials include official transcripts, a curriculum vitae or résumé, a statement of purpose outlining research interests and fit with faculty expertise, and academic or professional references. International applicants must meet Walden’s English proficiency requirements through recognised tests or equivalent documentation.

Additional expectations often include evidence of quantitative and research skills (for example, prior coursework in statistics or research methods), and a preliminary research idea or area of concentration. Some applicants may be invited to an interview with programme faculty to discuss research fit and readiness for doctoral study.

Career prospects

Graduates of this PhD programme are prepared for a range of research, academic and senior professional roles. Common career paths include university faculty and postdoctoral research positions, research scientist or data science roles in industry and government, chief information officer and senior IT leadership, cybersecurity director, consultant in systems design and information strategy, and policy or research roles at think tanks and non-profit organisations.

The programme’s emphasis on original research and publication also positions graduates for careers that require strong analytical, methodological and communication skills, including roles in applied R&D, product strategy, and evidence-based policy development related to technology and information systems.
