I’m Liam Guest—a product-focused data scientist building practical, user-facing tools at the intersection of geospatial data, machine learning, and public impact.
I’m strongest when the problem is messy: I translate ambiguity into clear product direction by aligning stakeholders, defining success metrics, and shipping iterative solutions grounded in data and real user workflows.
Recently, I’ve led AURA (AI for Urban Resilience & Alerts), a funded project exploring explainable, census-tract-level storm risk modeling to support preparedness decision-making.
Based in Chicago and open to San Francisco (and other major hubs).
