I’m a GeoAI researcher and educator working at the intersection of machine learning, geospatial data, and community participation. As an Assistant Professor at the University of Twente, I teach courses on scientific programming and machine learning, and I coordinate the GeoAI module of the UNIGIS Master’s program. My research focuses on data-driven methods for evidence-based decisions, from mapping smallholder farming systems with cloud-based multi-temporal ensemble classifiers to using high-resolution imagery to improve the SDG indicator on open spaces. 

I also care about communities. I love working in participatory settings and developed OGITO, an open, interactive geospatial tool that supports collaborative spatial planning with a maptable. As an active member of the QGIS community, I teach hands-on open-source GeoAI workshops at FOSS4G to help make these methods accessible to everyone. I’m also passionate about bringing more women into STEM

I am a Computer System Engineer, holding two master’s degrees in computer science and Geoinformatics from the University of Simon Bolivar and the University of Twente, and a PhD in urban planning.  Before joining ITC, I served as deputy president of the Geographic Institute of Venezuela, where I worked across GIS, remote sensing, spatial databases, and spatial data infrastructure.
