As a Research Associate (Data Science), I built predictive models and collaborated closely with healthcare stakeholders. My role involved end-to-end data workflow management, model evaluation, and translating results for both technical and non-technical audiences. Strong analytical, Python programming, and stakeholder management skills were essential in this position. • Developed logistic and gradient-boosted models for clinician-annotated health data • Presented model metrics and feature drivers using SHAP for interpretability • Created reproducible Python pipelines and standardized analytics outputs • Worked with clinicians and PIs to convert insights into actionable next steps
