I have graduated as a surveyor at the University of Architecture, Civil Engineering and Geodesy (Bulgaria) and obtained my PhD degree on 3D GIS for Urban Development at the Graz University of Technology (Austria). I worked as a software programmer at the Central Cadastre (Bulgaria) and have been at academic positions at UACG (Bulgaria), the Institute for Geo-information Science and Earth Observation (ITC, the Netherlands), Graz University of Technology (Austria), Delft University of Technology (the Netherlands) and Siberian State University of Geosystems and Technologies (Russia). I have joined the University of New South Wales in January, 2018.

I supervise master and PhD students on topics related to 3D spatial modelling and analysis. My recent research concentrates on 3D Indoor modelling and navigation. I am an author and co-author of more than 300 papers and I have edited and co-edited 23 books. A full list of publications (downloadable) is available here. I have been involved in the work of several international organisations. I am the president of ISPRS TC IV on Spatial Information science, the treasurer of UDMS and a co-chair of OGC SWG IndoorGML. I have been actively participating in the organisation of conferences such as Gi4DM, UDMS, 3D GeoInfo, Indoor3D and summer schools.

In my free time I am walking, hiking, cycling, swimming and reading.
