Rey Johnson works as an HDD Analyst for 3M Health Information Systems where he develops software solutions to meet interoperability needs for health data. He led the technical work on patient consent management which forms a critical portion of 3M’s recent patent application “Shared Revocation Ledger for Data Access Control.” He joined 3M in 2018 at the conclusion of a software engineering internship where he built a modern ETL pipeline to load medical terminologies into the Healthcare Data Dictionary, a FHIR-compatible terminology server.
Rey is pursuing a Master of Biomedical Informatics at the University of Utah, where he is studying machine learning, FHIR-based interoperability, and visualization techniques for healthcare data. As an undergraduate student, he studied cryptography and blockchain technology and he holds a Bachelor of Science in Finance. Since learning to code at eight years old, Rey has maintained a lifelong interest in applying technology to improve life. His current focus on
interoperability in health data reflects his commitment to building an accessible, patient-centered healthcare system.
