GEOquery
The bridge between the NCBI Gene Expression Omnibus and Bioconductor — a foundational R package I've maintained for years, used across the genomics community. Docs Paper
Physician-scientist — open software and data for cancer research.
For almost two decades I've built open tools, curated the public biomedical record, and now build AI agents that help researchers find and use it. Core Bioconductor packages I steward bridge the field's largest data archives: in 2025, GEOquery alone was downloaded 314,396 times from 112,736 distinct IP addresses.

I'm a physician-scientist and Professor of Medicine and Biomedical Informatics at the University of Colorado Anschutz Medical Campus, where I hold the Rifkin Bennis Chair of Cancer Informatics and am Associate Director for Informatics and Data Science in the Comprehensive Cancer Center. I'm board certified in pediatrics and hold an active medical license.
I build open data infrastructure and AI tooling for cancer research, maintain long-standing software in the Bioconductor project, and help lead community open-science efforts. Reach me through any of the channels below.
