Narratives in numbers.

Forecasts, causal readouts, and evaluations of AI-generated analyses built for decisions, not reports.

I am a Senior Data Analyst at Kit and a Time Series and Forecasting professor at IE University. My work produces forecasts across statistical and foundation models, causal readouts from experiments and observational studies, and evaluations of AI-generated analysis for correctness and decision-readiness. The goal: analysis a team can act on. Semantic layer design is part of the infrastructure behind that work.
