FORMATION

  • 2008 PhD degree, University of Toronto, Department of Geography and Program in Planning, Toronto, Ontario, Canada
  • 2003 MSc GIS degree, University of Salzburg, Department of Geoinformatics/UNIGIS, Salzburg, Austria
  • 2001 Dipl. geol. degree, Karlsruhe Institute of Technology, Department of Applied Geology, Karlsruhe, Germany
THÈMES DE RECHERCHE

Mes principaux intérêts scientifiques portent sur la compréhension des altérations dans les interactions entre la biosphère et l'atmosphère en réponse aux changements environnementaux mondiaux, utilisant des mesures par exemple : des mesures de covariance des turbulences), la télédétection (satellite et près de la surface) et les techniques de modélisation. Je suis également intéressé par la mesure locale et la cartographie (régionale, mondiale) des paramètres biophysiques pour étudier les changements dans la structure, le fonctionnement et la phénologie des écosystèmes terrestres.
