Areas of knowledge

  • Agricultural Systems & Remote Sensing
  • Research & Development
  • Vegetation & Environmental Monitoring

Education

M.Sc. in Sustainable Resource Management (Specialized in geo-spatial big data management), B.Sc. in Agricultural sciences (EARTH University –  Costa Rica), and Technician diploma in accounting and finances (C.T.P.H. – Costa Rica). Currently advancing a PhD program at Bonn University.

Areas of expertise

My expertise bridges geospatial big data analysis and visualization, agricultural research, production systems and grid-based environmental modeling. With a foundation in accounting and project management, I bring both technical and operational skills to interdisciplinary sustainability projects. My focus is on advancing
precision agriculture and forestry through big data processing, sensor-based fieldwork, and large-scale environmental monitoring. I’m particularly interested in contributing to projects where remote sensing technologies and data-driven methods can support sustainable resource management and bioeconomy.

Background

I am a project manager and researcher working at the intersection of agriculture, remote sensing, and sustainable resource management. My career began in Costa Rica, managing agricultural enterprises focused on urban plantations, insect farming, and cattle management. In Peru, I developed biological control methods for banana pests, while in Brazil I collaborated with the National Institute for Space Research on satellite imagery projects.

In recent years, my work has centered on applying sensors and satellite data to environmental monitoring. I’ve contributed to interdisciplinary research in Germany, developing tools for drought detection in forests and mapping forest change across Europe. My work at GAF AG supported REDD+ programs in Cambodia, Mozambique, Ethiopia, and Paraguay, while in consultancies I quantified forest change at continental and planetary scales with institutions such as the University of Trento and PUCP.

Currently pursuing my PhD at Bonn University, I work with advanced sensor systems, spanning leaf, canopy and aerial platforms to investigate solar-induced fluorescence: the subtle light signal emitted as sunlight is converted into living plant biomass.

Interesting fact about you

When I was 20, I spent every afternoon of a 4-months internship in Perú walking the forest trails in my quest to see the jaguar in the wild.

Favorite Quote

“If we lose the environmental fight, no other fight will make sense”.
Supporting good ideas from people in social, political and economic disadvantage is a must to achieve a global sustainable development. Sustainability works better in cross-border teams. If the innovative idea of a person to improve his environment doesn’t receive support, possibly there will be nobody doing that. We believe in these ideas and want them to flourish and spread.
