PhD Student in Systems and Computer Engineering
Visiting Ph.D. Research Intern at Université Laval / CERVO
Data Science ResearcherI am a mathematician with a strong background in applied modeling and computational analysis. My current work focuses on the integration of uncertainty-aware predictive models into decision-making processes for complex systems.
Through my doctoral research, I focus on integrating uncertainty into predictive models to improve decision-making in emergency response systems. I study how incomplete information and intervention-induced behavioral changes affect planning and resource allocation. At DataLab, I contribute to the development of data-driven tools for assessing health risks, optimizing interventions, and supporting public sector decision-making.

Quantifying Predictive Uncertainty in Crime Forecasting using Conformal Prediction
Cristian Pulido, Francisco Gómez
Accepted at 19° Congreso Colombiano de Computación (CCCesp 2025) SecurityUncertainty
This work presents a model-agnostic framework using Conformal Prediction to generate calibrated prediction intervals for crime hotspot forecasting. Applied to Chicago data, it reveals spatial variations in prediction confidence, highlighting the value of uncertainty in decision-making.

A Question-Driven AI Framework for Early-Stage Territorial Decision Support
Cristian Pulido*, Oscar Sánchez*, Diana Aldana, Juan Diego Murcia, Sarah Coral, Francisco Gómez (* equal contribution)
Accepted at 19° Congreso Colombiano de Computación (CCCesp 2025) Spotlight Decision Support
This work introduces a modular AI framework combining guiding questions with LLM-based assistants to support early-stage territorial planning in Colombia. Two assistants—traditional RAG and agentic RAG—were evaluated, showing improved response quality and usefulness.

Quantifying perception of security through social media and its relationship with crime
Luisa Fernanda Chaparro, Cristian Pulido, Jorge Rudas, Jorge Victorino, Ana María Reyes, Camilo Estrada, Luz Ángela Narváez, Francisco Gómez
IEEE Access 2021 Social Sensing
This study proposes a machine learning model to quantify the Perception of Security on Twitter using sentiment analysis and crime-related filtering. Results reveal meaningful distinctions from traditional content-counting methods and dynamic links with specific crimes like robbery.
