  1. Doctorate in Applied Mathematics University of Montpellier II >University of Leicester > University of Greenwich >Sanofi-Recherche Montpellier >fMRIB University of Oxford > post-master in Information & computing science>IRD - Maison de la Télédétection (Remote Sensing House)…  • interests in modelling & analysis of spatio-temporal dynamics: • regional scale: ecoregion clustering (climatic, ecologic and societies) • local scale: landscape changes (land cover/land use and integrated modelling) • changing scales extrapolation Dr DidierLeibovici

  2. from spatio-temporal data analysis … Doctorate of Applied Mathematics UMII > University of Leicester> • auto-correlations and spatial structures, e.g. long time series of Asthma mortality INSERM Montpellier (1990 - 1994) • «Repeated Measures Factors and multidimensionnal Analysis: application to a HIV+ follow-up study, SEROCO»(thesis defended in 1993) INSERM Montpellier (1990 - 1994) • Cognitive ageing and risk factors (the longitudinal study Eugéria) INSERM & Department of Epidemiology, Leicester (post-doc 1994-1995) 9 papers,2 chapters, 7 communications, 1 package, 1 thesis Epidemiology, longitudinal, linear model, logistic model, automatic clustering variance analysis: univariate,multivariate, tensovariate Dr DidierLeibovici

  3. from spatio-temporal data analysis … >University of Greenwich U.K. > Sanofi-Recherche Montpellier >fMRIB University of Oxford U.K. > • tensorial decomposition (PTAk) in infinite dimension, multivariate distribution analysis • University ofGreenwich (Research fellow 1995-1996) • multiway tables analysis and quantified-EEG in pharmaco-dynamic studies (phase IIa) Sanofi-Recherche (Statistician Researcher 1997-1999) • models and analysis of multi-subject fMRI brain imaging experiments University ofOxford (Research fellow 1999-2001) 6 papers, 3 abstracts,5 communications, 2 packages, 6 reports functional spaces, multiple contingency tables, spatial signal, repeated observations, tensor analysis, image sequences, mixed model, multiple comparisons and Gaussian Random fields Dr DidierLeibovici

  5. to geomatic modelling of dynamics > post-master (DESS) in Information & Computing sciences>IRD (Research Institute for Development) - Maison de la Télédétection (Remote Sensing House) … • Information Systems, UML modelling, data structures algorithms, java, www University of Montpellier II (2001-2002) • spatialised environmental modelling: SIEL (ROSELT program) Système d’Information de l’Environnement Local : GIS database + models Réseau d’Observatoires de Surveillance Ecologique à Long Termes: 14 countries (circum-sahara), 30 observatories as research and operational platform IRD US «Désertification» (since 2002) • coupling models for landscape dynamics (DeSurvey-IP FP6 program) Desertification Survey : 40 European teams, , 4 in Africa1 in China, 1 in Chile IRD US «Désertification» (since 2005) 6 papers (in progress), 1 abstract,4 communications, 2 packages, 2 reports objectconception, geomatics, GIS, spatialisation algorithms, Multi-Agent System, resources/usages dynamics, arid and semi arid zones, network of observatories approach, integrated modelling Dr DidierLeibovici

In progress 1st author A method to Classify Ecoclimatic Arid and Semi-Arid Zones in Circum Saharian Africa Using Dynamics of Multiple Indicators.(GIScience and Remote Sensing) Ecoregion Delineation Model for Circum-Sahara ecological Monitoring of Desertification. (International Journal of Geographical Information Science) A Landscape Modelling decision tool for desertification assessment using a Local Environmental Information System(SIEL). (Environmental Modelling & Software) co- author Concepts and Methods to restructure the landscape according to resources/uses interactions. (Landscape Ecology) Integrated environmental and socio-economic modeling using SIEL for desertification monitoring and assessment in the observatory of Menzel Habib (South Tunisia). (Journal of Arid Environments) First results on assessing and predicting anthropogenic pressure on vegetation using SIEL/ROSELT at the observatory of Ferlo (Senegal).

  9. geospatial interoperability for spatio-temporal dynamics > work related to GEOSS objectives • ROSELT general approach www.roselt-oss.org • DeSurvey coupling or chaining models (DeSs) www.desurvey.net • SIEL integrated modelling GIS tool www.roselt-oss.org • MDweb metadata cataloguing (advanced and cartographic queries) www.mdweb-project.org - ISO 19115 - distributed searching «service» (Z3950 service ISO 23950) - semantic expansion searching (spatial and disciplines ontologies) - semantic network building Dr DidierLeibovici

  10. geospatial interoperability for spatio-temporal dynamics > research thoughts towards GEOSS • model building system aspects: integrated modelling and SOA GEOSS user orientated WRS … model building interface facilities • intelligence of it: semantic and metadata for services WRS, UDDI … appropriate catalogs for GEOSS towards Multi-Agent System modelling • technical aspects: SOA what about performance for GEOSS ? GeoServer (using GeoTools) and WFS –T (transactional) WPS for models (recent OGC adoption) links with www.openMI.org (HarmonIT FP5) Dr DidierLeibovici
