Expert Environnement milieu biologique

Tiphaine, docteure en écologie diplômée de l’Université de Rennes 1, a rejoint l’équipe d’ORYX EXPERTISE GUINEE en tant que chargée de projet.

Sa thèse en entomologie et invasions biologiques à Kerguelen lui a donné le goût du terrain et sa rigueur scientifique. Elle s’est ensuite orientée vers l’analyse de données plus générales sur le patrimoine naturel au Muséum national d’Histoire naturelle de Paris et à l’Office français de la biodiversité. Elle y a participé au développement d’outils statistiques à destination des pouvoirs publics et du secteur privé pour les assister lors des études d’impacts environnementales.

Elle met à profit ses connaissances poussées en écologie et sa curiosité naturaliste pour assurer le suivi des études qui lui sont confiées, la coordination des consultants sur le terrain et la compilation des données et productions écrites.
