Biography

I am the Chief of Data Science and a Data Architect at the Arizona Geological Survey and the University of Arizona. I currently oversee a team of GIS specialists, research scientists, systems administrators, and software developers. We specialize in full-stack deployment of large-scale databases of geological information, and work on or have worked on the following major geoscience initiatives - international geologic map database (macrostrat.org), geoeducational research (flyovercountry.io), geothermal datasets (data.geothermaldata.org), scientific publications (geodeepdive.org), paleontological data (paleobiodb.org), and others.
