Data Workflows, Documentation, and Quality
Build and implement data workflows in coordination with internal IT and external data partners, following established processes for access, secure storage, audit logging, permitted use, onboarding, and data transfer.
Maintain clear documentation of data definitions, source systems, data transformations, statistical methods, assumptions, quality checks, and results so that work can be reviewed and reproduced.
Apply appropriate quality-control practices to datasets, analyses, programs, and outputs, escalating material issues and risks in a timely manner.
Contribute to the development and continuous improvement of standards, templates, workflows, and best practices for data science and biostatistical analyses.
Cross-Functional Collaboration and Communication
