The Ph.D. Specialization in Computational Social Science brings together classes and community across the Division of Social Sciences. The CSS Specialization supplements social science Ph.D. curricula with technical coursework and practice leveraging modern computational modeling methods and large naturalistic datasets. These skills, in turn, deepen understanding of the core theories and applications of their home department field, and provide marketable, technical, project-based expertise that can be applied to problems across academic, public sector, NGO, and business worlds. This specialization contributes to a more integrated and supportive CSS ecosystem at UC San Diego.
