FORMATION

• Ph.D. in Remote Sensing, 2006 (University of Alberta)
• M.Sc. in Remote Sensing and Ecology, 2003 (University of Alberta)
• B.Sc. in Earth Science and Anthropology, 2001 (University of Alberta)

THÈMES DE RECHERCHE

My main research interests include ecological applications of remote sensing, forensic applications of remote sensing, hyperspectral data analysis, machine learning (pattern recognition, Bayesian Networks, classification), spatial modeling and tropical ecology.

My current focus for the upcoming year is to apply high performance computing (HPC) systems to high dimensional remotely sensed data from airborne and satellite platforms. Furthermore I will address the question of optimizing algorithms for CELL based processor clusters and GPU (graphical processing unit) processors for near real-time processing of airborne hyperspectral imagery.
