I’m a data scientist and software developer at Stanford’s Department of Health Policy, where I build Bayesian calibration models and decision-analytic tools for cancer screening research. My work spans gastric and colorectal cancer — modeling H. pylori eradication strategies, projecting the long-term impact of colorectal screening guidelines, and translating clinical evidence into policy-relevant models. I hold an MSc in Data Science for Public Policy from the Hertie School and am part of the colorectal and gastric cancer groups within CISNET, the NCI’s Cancer Intervention and Surveillance Modeling Network.

Before Stanford, I held research positions across Mexico and Germany. At CIDE’s Drug Policy Program, I built datasets on organized crime — mapping 148 criminal groups and geocoding thousands of violent incidents — work that reached national and international media. At CISIDAT, I built Bayesian and survival models for H. pylori, COVID-19 mortality, and homicide trends in Mexico. At the Hertie School Data Science Lab, I built scrapers and structured datasets for NLP and LLM research.

I build open-source R packages for health economic research and am developing AI orchestration systems — multi-agent pipelines connecting language models to health modeling workflows.
