Professor of Geography in Geomatic and Spatial Analysis

Aix-Marseille University (AMU), Faculty of Art, Literature and Social Sciences





Research Areas

My area of research concerns the analysis of the processes of urbanisation, territorial development, and metropolisation in the context of the globalisation, climate changes, and adaption in the post-soviet countries (Baltic, Russian Federation), Arctic and Sub-Arctic regions; but also before in the territories in transition (Africa, India, and The Maghreb).

Geographic Analysis are based on the development and implementation of remote sensing spatial monitoring systems (Hyperspectral, Hight spatial resolution, Image processing, morphometry, artificial intelligence, massive data, etc.), multi-temporal geographic knowledge systems, and spatial simulation.
