Research interests: survey sampling and inference under complex designs, inference with nonprobaility surveys, small area estimation, inference with non-probability samples, record linkage and census coverage evaluation, and inequality and poverty measurement.

FGV-IBRE (2025)

  Series of methodological reports for the Superintendência de Estatísticas Públicas. They cover many themes, including: sample size determination for price index surveys and for the estimation of proportions, including simultaneous estimation of multinomial proportions; and statistical inference for survey data, including methods for non-probability samples and tests of homogeneity across independent surveys.
