Abstract
This article highlights my research as a trainee with Dr. James C. Hogg, particularly on developing and investigating quantitative computed tomography (CT) imaging biomarkers of the small airways in chronic obstructive pulmonary disease (COPD). Together with Dr. Hogg, we developed a quantitative CT imaging measurement, termed the CT total airway count (TAC), using standard image acquisition and commercially available software. We showed that the CT TAC measure was significantly associated with lung function decline, reflects the reduction in terminal bronchioles in the same lung in COPD, and can be used to predict progression to COPD in current or former smokers with normal lung function. This work also fostered collaborations that extend investigation of quantitative CT airways to healthy aging and lung development research. Dr. Hogg’s legacy continues to inspire the development of novel imaging biomarkers for COPD risk and progression that may ultimately improve outcomes for individuals with COPD.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
