Columbia University

What you'll study

The programme combines intensive coursework in theory and methods with supervised independent research leading to a doctoral dissertation. In the early years students take core seminars in classical and contemporary social theory, advanced quantitative methods (including statistics and causal inference), qualitative methods (ethnography, interview methods, archival research), and research design. Students typically choose one or more substantive fields such as stratification and inequality, race and ethnicity, culture, organisations and work, family and demography, urban sociology, political sociology, or social psychology.

Beyond core courses, the curriculum emphasises methodological breadth: modules and seminars cover multivariate analysis, longitudinal methods, experiments, network analysis, computational social science and mixed-methods approaches. The department also offers seminars and workshops in writing, teaching, and grant preparation, as well as a regular department colloquium where faculty and visiting scholars present current work.

After completing required coursework, students prepare for qualifying examinations (written and/or oral) and develop a dissertation prospectus. The dissertation is conducted under the supervision of a faculty committee and culminates in an oral defence. Throughout the programme students engage with interdisciplinary centres and resources across the university, such as population research, urban research centres, public policy and public health units, which support specialised data, fieldwork and collaborative projects.

Entry requirements

Successful applicants typically have a strong academic record in sociology or a closely related discipline, with evidence of preparation in social theory and empirical methods. A master’s degree in sociology or a related field strengthens an application but is not always required; many admitted students also arrive with a research-focused master’s. Admissions committees look for prior research experience (for example a research assistantship, thesis or published work), clear research interests, and the potential to complete an original dissertation.

Application materials generally include official transcripts, a curriculum vitae, a statement of purpose outlining research interests and fit with the department, a writing sample (such as a research paper), and letters of recommendation (commonly three) from academic referees. International applicants must demonstrate English proficiency according to university policy. The department assesses applicants on intellectual preparation, methodological skill, clarity of research agenda and potential for independent scholarship.

Career prospects

Graduates of the PhD programme pursue a range of careers. Many obtain tenure-track academic positions in sociology and related departments, teaching and continuing research. Others work in research-oriented roles at policy institutes, international organisations, government agencies, non-governmental organisations and think tanks, where they apply sociological methods to public policy, social programmes and evaluation. Graduates also move into applied research and data-intensive roles in the private sector, such as data science, market and social research, and consulting, or into leadership roles in philanthropy and advocacy organisations.
