01 / RESEARCH DETAILCandidate physiomarkers of individual craving responses

Challenge
Craving responses differ in magnitude and direction across individuals, limiting a single marker's explanatory power.
Approach
Synchronized video stimuli, questionnaires and physiological signals, then compared individual correlations and changes across craving levels.
Contribution
Designed acquisition and quality checks at two hospitals. Conducted LMM and SHAP analyses in the expanded cohort.
