Physician-scientist — open software and data for cancer research.

  • MD, PhD · Professor of Medicine and Biomedical Informatics, University of Colorado Anschutz Medical Campus
  • Rifkin Bennis Chair of Cancer Informatics
  • Associate Director for Informatics and Data Science, University of Colorado Cancer Center

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.
