Activités professionnelles / intérêts

À l’instar de nombreux chercheurs du gouvernement du Canada, j’entretiens des liens étroits avec le milieu universitaire. Je travaille comme professeur de recherche auxiliaire au  Département de géographie et d’études environnementales de l’Université Carleton, où j’exerce les fonctions d’enseignant et supervise des étudiants depuis 2003. Mon rôle à l’Université a récemment été élargi pour inclure le poste de scientifique adjoint au Laboratoire de géomatique et d’écologie des paysages (GLEL).

Je continue d’appuyer activement la communauté de la télédétection en participant aux travaux  de divers organismes nationaux et provinciaux dans ce domaine. J’ai été membre du Comité exécutif national de la Société canadienne de télédétection (SCT) de 2008 à 2013 et président du Groupe de travail sur les communications de la SCT de 2013 à 2015.

En novembre 2013, j’ai élu au Collège des Fellows de la Société géographique royale du Canada. La SGRC se consacre à faire mieux connaître et apprécier le Canada, sa population et sa géographie, son patrimoine naturel et culturel ainsi que ses défis environnementaux, sociaux et économiques. Elle représente l’une des plus importantes organisations éducatives sans but lucratif au Canada et elle se finance principalement grâce aux frais d’adhésion et aux dons généreux qu’elle reçoit. Son conseil des gouverneurs et ses comités de programmes sont entièrement composés de bénévoles.
