Educational Researcher


Hello! My name is Diego Campos. I am a Researcher at the Centre for Educational Measurement at the University of Oslo (CEMO). My work involves developing, evaluating, and applying methodological approaches —IPD meta-analysis and ML— to integrate large-scale data into systematic reviews and meta-analyses. My current research applies these methods to understand trends and variance in educational inequalities across education systems and over time.


I am currently a researcher at the MapIE project (Mapping of Longitudinal Data of Inequalities in Education). MapIE is a Horizon Europe funded research project spanning across five Nordic and Central European countries for the period between 2024–2027. In the project we aim to identify what mechanisms cause inequalities in education and what policy measures and interventions exist to compensate for them in the context of the Nordic and Central European countries. Within national contexts and using comparative research design, we address the system-, regional-, and school-level policies and practices, and pupil-level individual factors (such as socioeconomic status, gender, etc.) that contribute to the development of educational inequalities in secondary education in the Partner countries.
