Stephan Winter is Professor in Spatial Information Science at the Department of Infrastructure Engineering, The University of Melbourne, Australia, and currently also Visiting Professor at IIT Kanpur, India. He holds a PhD (Dr.-Ing.) from the University of Bonn, and a habilitation from the Technical University Vienna. He is specializing on human spatial cognition and communication, with a vision of developing intelligent spatial machines especially in the context of indoor and outdoor spatial modelling, wayfinding, navigation, and intelligent transport. He is pioneering formal as well as stochastic models of mobility within these environments. He contributed to the formulation of intelligent spatial systems, computational transportation science, and probabilistic time geography. He is also senior member of the Institute of Electrical and Electronics Engineers (IEEE – ITS Society), member of the Association for Computing Machinery (ACM – SIGSPATIAL), and member of the ISPRS International Scientific Advisory Committee (ISAC).
