I am an urban data scientist postdoctoral researcher at Delft University of Technology with a PhD in Urban Building Energy Modelling using Semantic 3D City Models and open data. My work explores the potential of open data and semantic 3D city models to enhance energy-related urban analyses, ranging from solar energy assessment to comprehensive evaluation of building energy performance. I integrate machine learning and geospatial analysis to harmonise and process large-scale heterogeneous datasets, enabling more accurate urban building energy modelling. My research addresses key challenges such as the integration of spatial and non-spatial data sources and the development of tools that link these data with urban energy simulation models.
