Lens 4 of 4: Data Science & Platform Engineering

Real-World Data Scientist

Eight-plus years wrangling and analyzing large-scale EHR and administrative claims data, including hands-on analysis at a 150-million-patient scale, using SQL, R, and Python. I scope analysis requests, deliver against agreed deadlines, and am my team's Truveta subject-matter expert: I independently mastered the platform, including Truveta Studio and its proprietary Prose coding language, within roughly three months of gaining early access, and have since trained five-plus colleagues and built Jupyter- and Databricks-based analyses across multiple disease areas.

Core expertise

  • Real-world data and EHR analysis at scale. Wrangling and analyzing large-scale EHR and administrative claims data using SQL, R, and Python to scope and deliver on deadline.
  • Truveta platform mastery. Truveta Studio and its proprietary Prose language, learned independently and then taught to colleagues at junior and senior levels.
  • Notebook and pipeline development. Jupyter- and Databricks-based analyses, including regex query writing and Spark/PySpark, across disease areas spanning C. diff, COVID-19, RSV, influenza, healthcare-associated infections (HAIs), and UTIs.
  • Multi-platform data engineering. ETL pipeline design and data modeling across Truveta, MarketScan, CMS claims, PointClickCare, Premier/PHD, Epic, and Cerner.

Honest scope note: my Truveta and Databricks work has been analytic and platform-enablement focused, not machine learning model development, and I have not worked with de-identification or quasi-identifier methods on Truveta data.

Experience

2022–Present
Scientific Data Analyst & Truveta Subject-Matter Expert
Chenega Professional Services SBU, supporting CDC DHQP, Atlanta, GA
  • Directly utilize the Truveta real-world data platform, integrating it with MarketScan, CMS, PointClickCare, and Premier to evaluate COVID-19 vaccine effectiveness, safety, and breakthrough infections across a multi-million-patient EHR database.
  • Became the team's Truveta subject-matter expert after being among the first granted platform access, independently mastering Truveta Studio and Prose within roughly three months.
  • Built Jupyter- and Databricks-based analyses, including regex query writing and Spark/PySpark, addressing research questions on C. diff, COVID-19, RSV, influenza, HAIs, and UTIs.
  • Trained 5+ colleagues at junior and senior levels to work independently within the Truveta platform.
  • Programs statistical analyses in R and SAS producing reproducible, well-documented code against agreed-upon deadlines.
  • Develops evidence synthesis reports, publication-quality tables, figures, and reusable documentation translating complex platform-specific data concepts into clear guidance.
