About

Forester by Education, Technologist by Interest, Nature Lover by Heart

I work as a forest scientist in the field of remote sensing and geospatial data analysis. Leveraging cutting-edge tools and technologies to integrate all kinds of spatial information for an in-depth analysis and advanced visualizations.

I am passionate about maps of all kinds and have recently developed a keen interest in Lidar data. Whenever possible, I advocate for the use of free and open-source software (FOSS) solutions, using RStats extensively and encouraging my colleagues to support and adopt FOSS.

I firmly believe that digital technologies hold immense potential to revolutionize our approach to environmental management and conservation.

I aim to contribute to a greener future.
