Research summary
He is a research scientist at the Luxembourg Institute of Socio-Economic Research (LISER) hosted at the Urban Development and Mobility department). He received his habilitation-HDR (2019), a full ADR (authorisation à diriger des recherches, 2018) from the University of Luxembourg, PhD (2007), Master (2004) in Computer Science from the Technology University of Compiegne (UTC-France). He has supervised several Ph.D. and Masters students. He serves as a reviewer for several international journals. During his LISER funded scientific leave (2016-2017), he served as a Senior Visiting Researcher at Purdue University (USA), working jointly with Dr. Pijanowski, an internationally recognized specialist in the field of land change science.
He conducts research in the framework of several competitive projects supported mainly by the Luxembourg National Research Fund (FNR). His research focuses on data science, complex systems modeling based on cellular automata, multi-agent systems models, multi-criteria decision making in complex, dynamic and uncertain environments, human mobility and transportation, policy evaluation, and urban studies and planning. He has published more than 100 scientific publications among them more than 40 articles in peer-reviewed journals, including the Journal of GIScience and Remote Sensing, Environmental Modelling & Software, Ecological modeling, Computers, Environment and Urban Systems, Environmental Informatics, International Journal of Geographical Information Science, Expert Systems and Applications, Computers & Industrial Engineering, and Applied Geography.
