At the Earth Observation Research Cluster (EORC), John Friesen develops Earth-observation-based approaches to analyse urban systems in the context of climate change, infrastructure planning and public health. His current work is strongly embedded in the EO4CAM project, where satellite data are translated into operational information for climate adaptation and mitigation strategies.
Originally trained in mechanical engineering, John’s research interest emerged from questions of infrastructure design and system optimisation in rapidly growing cities. This perspective led him towards urban geography and remote sensing as tools to better understand the spatial dynamics of urbanisation. In parallel, he studied medicine up to the first state examination, which continues to shape his scientific focus on the links between urban environments, infrastructure and health.
From Infrastructure Modelling to Earth Observation
John’s research combines engineering-based system thinking with geospatial analysis. His early work focused on modelling water supply infrastructures and spatial growth dynamics of informal settlements. Over time, this evolved into a broader research agenda that investigates urban morphology, accessibility to services, environmental exposure and climate-related risks using satellite data and spatial modelling approaches.
A central theme in his work is the development of quantitative methods to understand how socio-technical urban systems emerge, evolve and respond to environmental stressors. This includes research on informal settlements, urban heat exposure, climate resilience and access to healthcare in rapidly transforming cities.
Translating Satellite Data into Societal Applications
Within EO4CAM, John contributes to transforming Earth observation data into operational products that support decision-making in urban planning, environmental monitoring and climate adaptation. His current research also addresses regional climate challenges, for example by analysing urban heat mitigation strategies and ecosystem services in Bavarian cities.
Interdisciplinary Research for Resilient and Healthy Cities
At EORC, John collaborates across disciplines including remote sensing, geoinformatics, engineering and health sciences. His work aims to bridge the gap between satellite-based observations and practical applications for sustainable urban development. By integrating perspectives from infrastructure planning, spatial analysis and medicine, he contributes to advancing the understanding of how cities can become more climate-resilient and supportive of human health.
