Róza Vajda is a collection management associate at the Research Documentation Center (RDC). Within the ARP framework, she handles website editing tasks and develops informational materials. She also takes part in organizing and managing ARP events.

At RDC, she is responsible for curating the digital collections of the 20th Century Voices Archive, which gathers research materials—primarily interviews—produced by Hungarian social scientists using qualitative methods. She oversees the expansion of the archive's holdings and the modernization of its services. In line with advancing open science practices, her primary focus in both national and international projects is the development of thematic metadata.

With initial support from the Hungarian National Laboratory, she and her colleagues developed an NLP-based method to enable full-text searchability across the RDC archives' entire interview collection. Through this project, Vajda also became involved in the CESSDA ELSST (European Language Social Science Thesaurus) initiative. She is engaged in ONTOLISST, an international project led by RDC, which aims to align metadata structures for survey databases.

As a researcher, her interests include social relations shaped by ethnicity and gender, minority policies and social movements, the history of Hungarian sociology, and the scientific impact of processes unfolding under the banner of open science.
