I'm an environmental geologist and hydrogeologist with over 15 years spent between the field, the data, and the classroom.
I spent a decade working on soil and groundwater contamination — hydrocarbons and produced water — across Spain and Canada. Drilling programs, remediation systems, contaminant plumes, and the kind of analysis where a wrong interpretation has real consequences.
Along the way I noticed the same problem everywhere: powerful geostatistical methods locked inside expensive black boxes, or scattered across scripts nobody could audit. So I started building my own — modular R tools for QGIS that don't just compute a result, but explain their reasoning and generate reports you can defend.
Today I teach what I've learned. Through GeoRGB I've published over 150 tutorials and built 12 courses on geostatistics, QGIS mapping, satellite imagery and contamination analysis, reaching a community of more than 10,000 geoscientists and 3,500 students worldwide. I'm also the author of the Sampling Time QGIS plugin, downloaded over 2,100 times.
My goal is simple: to make rigorous, reproducible spatial analysis accessible to the people solving real environmental problems.
