Biographie

Formation

Ary Bruand est ingénieur agronome, diplômé de l’Institut national agronomique Paris-Grignon et titulaire d’un diplôme d'études approfondies de l'université Paris-Diderot. En 1985, il y soutient sa thèse de troisième cycle sur la structure des sols argileux et leurs propriétés hydriques. Il obtient son habilitation à diriger des recherches à l’université d’Orléans en 1993 et le grade de directeur de recherche à l'INRA en 1996[2].

Carrière d'enseignant

Il commence sa carrière en 1980 comme assistant à l’École nationale d’agriculture de Meknès (Maroc). En 1982, il entre au centre de recherche de Versailles de l’Institut national de la recherche agronomique (INRA). Chargé de recherche en 1985, il rejoint le service d’étude des sols et de la carte pédologique de France de l’INRA à Orléans et y développe un laboratoire de recherche en physique du sol. De 1990 à 1999, il dirige une équipe de recherche ayant pour objectif une meilleure connaissance des propriétés physiques des sols en fonction de leur composition.

Après une année passée à l’université d’Australie-Occidentale à Perth en tant que chercheur, il rejoint comme professeur l’université d’Orléans en 2000 et poursuit ses travaux au sein de l’Institut des sciences de la terre d’Orléans, qu'il dirige de 2006 à 2009. Il enseigne la géologie de surface et la pédologie à la faculté des sciences et à Polytech Orléans. De 2004 à 2006, il assure la direction du master géosciences et environnement qui regroupe trois spécialités, deux de la faculté de sciences et une de la faculté de lettres, langues et sciences humaines.

Ary Bruand est aujourd'hui professeur des universités en géosciences au sein de l'Observatoire des sciences de l'Univers en région Centre (OSUC) et du Collegium sciences et techniques de l'université d'Orléans.

Fonctions administratives

Ary Bruand assure les fonctions de coordinateur scientifique au sein de l’un des comités scientifiques disciplinaires du programme Blanc de l’Agence nationale de la recherche (ANR), unité support du CNRS, de 2006 à 2009. Il assure la présidence de plusieurs comités de visite de l'Agence d'évaluation de la recherche et de l'enseignement supérieur (AERES) au cours des années 2008 et 2009. De 2009 à 2012, il assure la responsabilité scientifique du secteur Environnement, terre-univers, espace au sein au sein de la direction générale Recherche et Innovation du ministère de l’Enseignement Supérieur et de la Recherche[2].

Il est vice-président chargé des relations internationales de l'université d'Orléans de 2008 à 2011, puis vice-président de son conseil d'administration, de 2011 à 2013. De 2014 à 2016, il assure la présidence du STUDIUM ainsi qu'une mission de conseil auprès du directeur de la recherche de l'Agence nationale pour la gestion des déchets radioactifs pour les questions relatives à l'environnement.

Membre du conseil d’administration depuis , après l'avoir été de 2002 à 2004, Ary Bruand est élu président de l'université d'Orléans le , succédant à Youssoufi Touré[3],[2]. Le , Éric Blond lui succède.
