What I'm looking for

I seek roles applying survey methodology and quantitative modeling to policy or product decisions, in teams valuing rigorous analysis, impact, and collaboration.

I am a statistician and economist with an MS in Statistics from The University of Chicago and over nine years of experience in economics, statistics, and data analysis across Chile and the U.S. I specialize in survey methodology, sampling, weighting, and applied analytics using R, SAS, and SQL, with experience deploying models and producing high-frequency deliverables for governmental and institutional stakeholders.

I have contributed to nationally significant projects, including weighting and estimation for large-scale immunization surveys used in federal COVID-19 response reporting, built production-ready predictive models with XGBoost, and led methodological updates for national indices, defending decisions before central bank and stakeholders. I work well under pressure, adapt to diverse teams and contexts, and bring clear communication of complex results to technical and policy audiences.
