Summary
👤
Senior🎓
Top SchoolRichard Zijdeman is a data-driven social historian and research leader with 12+ years of experience turning fragmented cultural heritage and historical datasets into interoperable, research-ready resources. As Chief Innovation Officer and Chief Data Officer at the International Institute of Social History and now a guest researcher at VU Amsterdam, he leads projects like the CLARIAH Structured Datahub that link micro-, meso- and macro-level socio-economic data through RDF. His research quantifies long-term changes in occupational stratification, gender segregation and household structures across centuries, combining digital humanities methods with sociology, demography and economics. Technically fluent in R, SPARQL, QGIS and multilevel modeling tools, he pairs methodological innovation (e.g., historical occupational coding and HISCI) with hands-on data curation. Colleagues rely on him for interdisciplinary project leadership and for enhancing dataset value by linking to external data centers. An interesting and less obvious strength: he blends deep historical expertise with practical RDF-driven data engineering to make centuries of social change machine-actionable.
