Personal profile
Personal profile
Hello! I am a remote sensing specialist for geoscience applications. I develop solutions for monitoring the natural environment and acquiring mineral intelligence on national to continental scales. Typical applications are the detection of critical raw materials and environmental pollution resulting from resource exploration, monitoring of landscape dynamics for public safety, and finding sources of green energy.
I teach courses in international environments. My speciality is to bring a research attitude to the classroom. My activities reflect my passion for education:
- online (e-learning) and classroom MSc & PhD courses;
- tailor-made courses on location (Africa, Asia, Latin America);
- supervision of MSc and PhD theses and mentoring students;
- vice-chair M-SE & M-GEO examination board.
My personal research interest is the development of practical solutions in remote sensing and image processing:
- Translating mineral characteristics to high spectral resolution indices acquired in the laboratory, which in turn are translated to the capabilities of freely available lower-resolution satellite imagery for large-scale and real-world applications;
- Using freely available satellite imagery for continental-scale geological mapping with simple methods, ensuring that anyone in the world can re-use and build on my findings;
- Analysis of multi-temporal data acquired from satellites and time-lapse cameras in the field to track changes at the earth's surface over time.
I care for my colleagues and students' well-being. I am a first-aid responder, and I am a very good listener.
