He is also an invited professor at the University of Porto, Portugal, and at the School of Architecture of Barcelona, Spain, where is concluding his PhD research on cellular automata modeling of urban systems. His research focuses on developing innovative urban planning approaches, particularly on the use of complex modeling tools to simulate urban and spatial phenomena, aiming to develop decision-support tools to help planners and stakeholders in common planning processes. He is currently editing a book on ‘Virtual Cities and Territories’ with IGI Global and he has recently organised CAMUSS, the International Symposium on Cellular Automata Modeling for Urban and Spatial Systems (more information at www.camuss.dec.uc.pt).
