What do you do with data science?

I have a multi-disciplinary program to improve health outcomes through the use of digital data to propel discovery, support improvement, and extend accountability. We leverage real-world data sources and protocolized data collection to create novel digital biomarkers and signatures and assays that can unlock insights in medicine. We also use varied digital science approaches to improve clinical trials and causal inference from observational studies. The goal is to bring together talent, data, and important questions to improve patient outcomes and the public’s health.
