Featured Project

RWE Explorer

A free, public curriculum in real-world evidence methodology.

Structured reading, runnable SQL against a synthetic dataset, and a final exam covering cohort construction, study design, safety, and regulatory standards.

Curriculum
Structured RWE Methodology

Cohort construction, study design, safety, and regulatory standards, sequenced for self-paced learning.

Hands-on
Runnable SQL Examples

Example codelists and queries against a synthetic dataset, so you can run the methods, not just read about them.

Assessment
Final Exam

A capstone assessment that tests practical understanding across the full curriculum.

At Pfizer, I served as the primary internal data expert on the COVID-19 RWE team, working directly with senior epidemiologists across the full study lifecycle. I designed and executed cross-therapeutic feasibility analyses in Snowflake across five major data sources, performed exposure-indexed outcome ascertainment for antiviral effectiveness studies, and authored study protocols and statistical analysis plans. During QC validation, I identified a vaccine CPT code misalignment that had caused systematic data errors, resulting in a full-year data credit from HealthVerity worth over $1 million.

At Target Real World Evidence, I built foundational expertise in RWE methodology while contributing to the development of CausalStudio, the company's proprietary causal inference platform then in active development. I extended existing codebases and implemented new functionality to support evolving analytical needs across the team.

At Duke University, I served as Senior Clinical Research Supervisor in the Brain Imaging and Analysis Center, where I designed and executed research pipelines for MRI-based cognitive aging studies. I processed and analyzed neuroimaging data using custom scripts on a Linux HPC cluster and authored study documentation, IRB protocols, and psychometric battery procedures.
