Aurore joined Sayari in September 2019. She holds a Master’s degree in Biology, specializing in « animal behavior and ecology & evolution » from the University of Neuchâtel (Switzerland) and a second Master’s degree in Environmental Engineering and Law. During her first Master’s degree, she carried out a wide range of field and laboratory research, focusing on marine environments and ecology. Her second Master’s degree was a work-study program between September 2019 and June 2021 at the Institut Supérieur de l’Environnement (ISE) in Versailles and Sayari.
Aurore has a good knowledge of marine ecosystems. She has conducted several research projects on the invasion of lionfish in the Caribbean, coral bleaching and overfishing of grouper in Belize. She has solid experience in project management (creation, coordination, project follow-up, writing reports and presentations), particularly in the field of ecology and biodiversity. She has an excellent command of databases and GIS tools.
She is an expert in life cycle assessment (LCA). Aurore contributes to projects run by the United Nations, in particular on « Life Cycle Impact Indicators (GLAM) ». She is also a member of the European Union’s Product Environmental Footprint (PEF) Technical Advisory Group (TAG). She is particularly involved in sustainable agriculture issues. She supervises interns and young students on semester projects.
She assists Sayari’s customers in assessing the environmental impacts (LCA and biodiversity) of their products and services throughout their value chain. She is a project engineer in the calculation of environmental metrics.
Grégoire collaborated with Sayari from 2019 to 2022 on the study of the impact of overfishing on biodiversity. A graduate engineer from Ecole Polytechnique (X18), specializing in Sciences for Environmental Challenges, he holds a Master’s degree in Marine Ecosystem Management from the University of St Andrews (Scotland). During his Masters, he studied the sustainability of human activities and solutions based on ecosystem functioning in various aquatic environments such as the North Sea, Guadeloupe and Lake Victoria.
Specializing in the marine environment but concerned by all environmental issues, Grégoire joins Sayari in September 2022 as an LCA and biodiversity consultant. Having studied in France, Iceland and Scotland, he brings his international experience and knowledge of the various scientific methods used to study biodiversity and ecosystem service issues. In particular, Grégoire is in charge of developing and enriching the methodology for assessing the biodiversity footprint of products.
He assists Sayari’s customers in assessing the environmental impacts (LCA and biodiversity) of their products and services throughout their value chain.
Iléane is at the end of her Master’s degree in Materials Science and Engineering at the Ecole Polytechnique Fédérale de Lausanne (EPFL). Concerned by sustainability issues, she has contributed to several LCAs and to the integration of the notion of sustainability into EPFL courses.
She assists Sayari’s clients in assessing their environmental impacts through LCA and biodiversity missions.

Aurore a rejoint Sayari en septembre 2019. Elle est titulaire d’un Master en Biologie, spécialisation « comportement animal et écologie & évolution” au sein de l’université de Neuchâtel (Suisse) et d’un second Master en Ingénierie et Droit de l’environnement. Durant son premier Master, elle a effectué de nombreux travaux de recherches en écologie sur le terrain et en laboratoire avec comme thématiques principales l’écologie et les milieux marins. Son second Master a été réalisé en alternance entre septembre 2019 et juin 2021 auprès de l’Institut Supérieur de l’Environnement (ISE) à Versailles et de Sayari.
Aurore possède une bonne connaissance des écosystèmes marins. Elle a conduit plusieurs projets de recherche sur l’invasion de la rascasse volante dans les Caraïbes, sur le blanchiment des coraux ou encore sur la surpêche du mérou au Bélize. Elle possède une solide expérience dans la gestion de projets (création, coordination, suivi de projet, rédaction de rapports et présentations) notamment en liens avec le domaine de l’écologie et de la biodiversité. Elle maîtrise très bien les bases de données et les différents outils SIG.
Elle est experte en analyse de cycle de vie (ACV). Aurore contribue en effet à des projets menés par les Nations Unies, en particulier sur les « indicateurs d’impacts sur le cycle de vie (GLAM) ». Elle est également membre du « Technical Advisory Group (TAG) » du « Product Environmental Footprint (PEF) » auprès de l’Union Européenne. Elle est plus particulièrement impliquée dans les sujets d’agriculture durable. Elle supervise des stagiaires et des jeunes étudiants pour des projets de semestre.
Elle accompagne les clients de Sayari dans l’évaluation des impacts environnementaux (ACV et biodiversité) de leurs produits et services tout au long de leurs chaîne de valeur. Elle est ingénieure de projet dans le calcul des métriques environnementales.
