Kevin Lan

Clinical Informatics & Real-World Data Specialist

PharmD by training, data engineer by trade. I came up through the CDC's Public Health Informatics Fellowship and spent the years since building OMOP CDM models and FHIR pipelines in Python, SQL, and R. My focus is real-world evidence and clinical interoperability, because claims and EHR data are only useful once someone's made them trustworthy.
