Field to Decision. Five systems, four decades, one discipline.

Applied data science that starts in field conditions and ends in decisions executives, regulators, and clinicians act on. Traffic sensors, dispensing cabinets, radioactive cargo, biomedical text. Each story closes with what it looks like in the 2026 stack, because the point of the past is what it builds next.
