Dr. Diana Zavala-Rojas is a social scientist interested in all aspects of the human data lifecycle. She is a specialist in multinational, multiregional and multilingual comparative surveys. She is the Deputy Director of RECSM.

She is a member of the Core Scientific Team (CST) of the European Social Survey (ESS) collaborating on questionnaire design, translation, measurement quality, cross-national measurement equivalence and documentation of the survey lifecycle. She has participated in the design and evaluation of ESS questionnaires since Round 6. She is also a member of the ESS Translation Expert Panel. 

Currently, she is leading the myESS software project, a collaborative environment to document data collection lifecycles and the ESS work programme on data comparability and question quality.  

Until 2022, she led a research project to improve the translation practices in multilingual survey projects in the Social Sciences and Humanities Open Cloud (SSHOC), exploring the use of machine translation and the creation of corpora of questionnaires in nine languages. Since the SSHOC, she also works on the implementation of the FAIR (Findable, Accessible, Interoperable and Reproducible) framework for the design and creation of research outputs.

She was a researcher in the Synergies for Europe’s Research Infrastructures in the Social Sciences (SERISS) project, studying the feasibility of applying computational linguistic methods to survey translation.

As a survey advisor, she has large experience in the design of survey projects for electoral campaigns. Before joining academia, she was an advisor for presidential campaigns in Mexico, and worked as a survey expert in the media. She collaborated as a public opinion expert at the Mexican Senate and the Mexican Congress. Diana has been a consultant for the World Health Organization (WHO) in Turkey and Spain.
