Lead Pedagogical Architect and Science Officer for the XODA system. Bilingual educator whose original request — a sentence analyzer for her classroom — became the founding question XODA was built to answer. Responsible for annotation schema validation, E3 calibration, and the pedagogical integrity of every diagnostic ruling. She named the need. The research grew from there.
