Diana is 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.
Her current research lines focus on 1) quality of cross-cultural survey data, analysing the effects of minority languages in the reliability and validity questions. 2) Language effects in surveys by studying multilingual measurement equivalence. 3) Survey translation and, 4) correction for measurement errors in survey research. Other research interests are experimental designs in survey research and structural equation modelling.
As a survey advisor, she has large experience in questionnaire design, measurement quality of survey questions and analysis of survey data. In her previous experience, she coordinated the electoral surveys of a national newspaper for the 2006's Mexican presidential election. She collaborated as public opinion consultant at Mexican Senate and the Mexican Congress. Diana has been consultant for World Health Organization (WHO) advising on projects in Turkey and Spain.
