03 — About

Research you can actually use.

The Informatics Lab pairs rigorous data science with user-centered design, so complex models become interfaces people trust, for providers, social workers, and patients alike.

Developed pipeline runs from raw EHRs to deployment: cleaning and integrating messy records into analysis-ready datasets, developing predictive models, and putting them in front of clinicians through digital twins, decision-support systems, and interactive dashboards.

Each system is built for real-world workflow integration, technology that enhances, rather than disrupts, how care is delivered. Research outputs have been presented at AMIA, APHA, ICHI, CHASE, PAKDD, and the College of Physicians of Philadelphia.

Research focus areas
