Senior Data Scientist
2019 - 2021CVS Health- Served as lead data scientist on various machine learning development, experimentation, and workforce innovation projects providing the incremental annual value of XX million USD.
- Responded to consistent urgent requests from the White House, CDC, and Operation Warp Speed leadership on capacity planning, second-dose adherence, and daily vaccine utilization.
- Implemented a fully customizable suite of COVID-19 vaccine demand forecasting and demand diagnosis models. These models anticipated vaccine demand drops and highlighted potential areas for intervention.
- Collaborated with lead designers to identify and address the impact of social determinants of health on low immunization rates, drawing on SHAP values and ethnographic data to design interventions.
- Acted as a key contributor to CVS's enterprise-wide algorithmic bias policy which set out steps for monitoring and mitigating bias along protected class lines within AI systems.
