Résumé

Daniela Mendirichaga

Los Angeles, CAdaniela.mendirichaga@gmail.comgithub.com/danielamendirichagalinkedin.com/in/daniela-mendirichaga

Master's candidate in Quantitative Economics (STEM) at UCLA, specializing in machine learning, experimentation and causal inference. Three years turning behavioral and transactional data into pricing and product decisions across international markets. Open to full-time data science, analytics or decision science roles from December 2026.

Experience

Research Analyst

Global Development Policy Center, Boston University

May 2022 – September 2025

Three years on a multi-project collaboration with Heineken, a global market leader in alcoholic beverages.

  • Cross-market experiments across 5 countries. Advertising, product placement and pricing interventions. Treatments moved the target KPI by 8 to 20 pp. Where real data was infeasible, I engineered LLM-generated, census-anchored synthetic datasets and built the price-sensitivity models on those.
  • Reproducible Python/R pipelines. Cleaning, feature engineering, modeling, evaluation. High-dimensional behavioral, transactional, survey and experimental data. This is what let the modeling scale across 10+ treatments and kept cross-functional reporting fast.
  • Advised senior Heineken leadership. Presented and defended experimental findings that shaped product, pricing and behavioral strategy. Coordinated reporting, data access and paper co-authorship across the IDB, BIT and OECD.

Research Assistant and Teaching Assistant

Economics Department, Anahuac University

Mexico City · August 2020 – May 2022

Applied econometrics & machine learning

Academic and replication work from the MQE and BS.

Causal inference & structural econometrics

  • Demand and supply in the pizza market. Structural demand and pricing model in pyblp; IVs isolate the causal price effect.
  • Dynamic pricing replication. Reproduced a published storable-goods model: volume discounts plus inter-temporal pricing lift profits 10%.
  • Data centers and electricity prices. County-panel OLS testing data-center activity against US residential electricity prices.

Discrete choice and willingness to pay

  • Camping park demand. Mixed logit (xlogit) recovering willingness to pay for amenities and travel time.
  • Transportation mode choice. Multinomial logit coded from scratch via MLE, benchmarked against logit and LPM.

Predictive modeling

  • Airbnb booking probability, Los Angeles. End-to-end pipeline benchmarking L1-logistic against XGBoost under a chronological split.
  • Used-car prices. Trees and XGBoost against an OLS/Ridge/LASSO baseline, compared out-of-sample.
  • Telecom churn. Logistic regression written from scratch, with bootstrap uncertainty estimates.

Forecasting

  • US construction employment. Prophet forecasts with seasonality and holidays, validated by rolling time-series cross-validation.

Education

Master of Quantitative Economics (STEM)

University of California, Los Angeles

Los Angeles, CA · September 2025 – December 2026

  • AI Agents Workshop: agents, tool calling, RAG and document intelligence, multi-agent orchestration, MCP-based deployment.
  • Advanced tracks in Econometrics and Machine Learning. Selective; top third of the cohort.
  • Departmental Merit Award, UCLA Economics.
  • Coursework: Machine Learning & Big Data for Economists; Advanced Machine Learning for Economists; Advanced Econometrics; Empirical and Mathematical Industrial Organization (the latter a PhD course); SQL & Data Management.

B.S. in Economics

Anahuac University

Mexico City · August 2017 – May 2022

  • Thesis: quantifying the tax-collection effects of Mexico's criminal-fiscal reform before its repeal. Modeled firm-level transaction behavior and estimated policy impact with difference-in-differences.
  • Fellowship, Universidad Anahuac.
  • Special Selection Award, CitiBanamex National Economics Prize nominee (2022).
