Guillou completed her engineering training at École Polytechnique (promotion X1973), and then specialized in water engineering at École nationale du génie rural, des eaux et des forêts (ENGREF, now known as AgroParisTech). She completed a PhD in physico-chemistry of biological processes at Nantes University (UA CNRS).

Food sciences edit

Guillou worked on food processes and invented a technique to monitor continuously the bio transformations of food products using physical chemistry sensors such as Nuclear Magnetic low resolution Resonance (NMR).

Food safety edit

She was in charge of the food safety directorate in France from 1996 to 2000. She had to manage the Bovine Spongiform Encephalopathy (BSE) crisis, also known as the mad-cow disease, and to propose the new French food safety organization (1999 law on food safety).

Research management edit

From 1986 to 1989, Guillou was Regional Delegate for Research and Technology in the Region Pays de la Loire. From 2000 to 2012, she was first CEO, then President and CEO of the French National Institute for Agronomic Research (Institut national de la recherche agronomique) where she prioritized research on agriculture, food and environment. She widened the scope of research topics towards global matters. She put in place interdisciplinary meta-programs, for instance on integrated plant protection and consumer practices.

From 2008 to 2013, Guillou was the chair of the Board of the École Polytechnique (l'X) and during her mandate, Ecole Polytechnique put a greater emphasis on the scientific and technological training, as well as the innovative management and the cooperation with industry. The creation of a new research center on interfaces between biology and engineering sciences was decided and financed and the organization of the Ecole Polytechnique was reformed.

Global involvement edit

Guillou founded the Joint Programming Initiative on agriculture and climate change ^[4] with British colleagues and chaired it during the first three years(2010-2013). This initiative, FACCEJPI, now gathers 21 European countries and links at international level with AGMIP and CCAFS. From 2013 to 2016, she was a member of the High-Level Panel Expert reporting to the Committee on World Food Security and a board member of the CGIAR. Starting in 2016, she became a member of the Bioversity board, and starting in 2019, she became a member of the CIAT board. She promoted the Alliance, an alliance between those two agricultural research centers.
