Welcome to my homepage! I am a Researcher at the Department of Evaluation, Measurement, and Educational Registry (DEMRE) in Chile, where I am part of the Modeling and Research Communication Team. I also conduct research at LIES – the Interdisciplinary Laboratory of Social Statistics – and lead ESIV Analytics®, a consulting company I founded that specializes in social data analytics.

My academic work focuses on the development of statistical models to evaluate predictive validity in the presence of selection bias and missing data. I study how selection processes shape the relationship between predictors and later outcomes, developing methodological approaches that account for partially observed populations and incomplete information. My research includes the predictive validity of admission tests, university retention and academic progress, as well as decision-making under incomplete data, survey analysis, and statistical models for measurement in educational and social contexts.
