09.2024 - Current
  • Transformed care management strategies with predictive modeling, optimizing resources by targeting high-impact patients, allowing care managers to focus on patients with the greatest needs, enhancing both cost-effectiveness and the quality of care provided, achieving 25% medical cost reductions through patient engagement.
  • Incorporated SDoH data, such as income, housing stability, and access to transportation, into the algorithm to improve predictions for patients facing barriers to care. This inclusion allowed for a holistic assessment of risk, increasing outreach success rates by ensuring that interventions accounted for the full spectrum of factors influencing patient health.

Senior Data Scientist

Aetna, a CVS Health
New York, NY
02.2019 - 08.2022
  • Performed a comprehensive program evaluation, revealing that the program saved an average of ~$119 per patient per month by reducing the frequency of hospital admissions and other high-cost interventions. This evidence of cost savings provided a strong case for expanding the program within Aetna's offerings and underscored the financial value of specialized care management.
  • Built predictive models to identify high-risk patients who would benefit most from the Accordant program, enabling proactive outreach and personalized care planning. This predictive approach improved patient targeting and enrollment efficiency, ensuring that resources were allocated to those with the greatest need.

Biostatistician

Montefiore Health System
Bronx, NY
11.2015 - 01.2019
  • Applied causal inference methods to assess program impact, adjusting for confounders such as comorbid conditions and social determinants of health. This analysis provided robust evidence that the Inspire program contributed directly to a 25% reduction in HCV incidence rates among high-risk populations.
  • Conducted a longitudinal analysis showing that participants in the Peer-to-Peer Diabetic Program achieved a 1.5-point average reduction in HbA1c levels over 12 months, highlighting the program's success in supporting sustained glucose control and reducing long-term complications in patients with diabetes.

Data Analyst II

Memorial Sloan-Kettering Cancer Center
New York, NY
08.2009 - 10.2015
  • Conducted case-control analyses using large datasets to identify risk factors associated with pancreatic cancer. The analysis uncovered correlations with paraneoplastic conditions (weight loss, new onset diabetes, fatigue, and depression), contributing to MSKCC's understanding of risk profiles and informing recommendations for high-risk population screening.
