As group leader (research project on ”Flower development and evolution”),
the research field covers plant developmental genetics and evolution, through collaborations in Belgium, Italy, Switzerland, France, UK, and USA.
The research investigates speciation mechanisms, sex determination and flower dimorphism, morphological innovations / optimizations, resources reallocation, phase change regulation and meristem termination, growth rate and biomass control.
Furthering the understanding of these evo-devo processes allowed me to focus the research on placenta development and evolution (with Michiel Vandenbussche, CNRS fellow and ATIPE project 2010-2014) and to revisit the biological productivity concept, a unique property of biological resources.

As teacher,
I am teaching or have taught molecular genetics and epigenetics, integrative plant biology, plant development and evolution, biodiversity and biological resources, history of sciences, and contemporary issues in science and society. I am supporting projects that show biological sciences as key to the transition towards a new eco-society and civilization.
I have dealt with bio-resources and agriculture essentially through two of my courses in the Bioscience Masters’ degree :

  1. “Science and society”, that takes the students through notions of ethics / responsibility and issues such as man-nature relationship ;
  2. An advanced course on “Bio-resources and biodiversity” during which invited experts discuss various topics within the resources problematic and public goods. The students and the pedagogic team perform personal work on various aspects of the course. At international level and in addition to bilateral exchanges with EU universities through the ENS international agenda, I am a contributor to the Anthropocene Campus in Berlin since 2013.

The interdisciplinary approach. Since 2009, as a member of the Institut universitaire de France (IUF), I centred my activity on an interdisciplinary approach to natural resources, because they constitute THE key issue of our society. Plants, as primary producers, set the baseline of biomass production on land ecosystems.
I joined the EVS geography laboratory and developed preliminary studies on agro-resources in the Rhône-Alpes region (2009-2011 ; Cluster “Quality of plants, agricultures, actors and territories”).
In 2011, I organized the IUF conference on “Resources” in Lyon, dedicated to an update of the disciplinary perception of the resources concept (iuf20ans.org ; Les ressources – Resources (2011).

To that end, I created the Michel Serres Institute for Resources and Public Goods at ENS Lyon in 2012, where I coordinate the work of students and colleagues from life sciences, economy, and legal studies towards an integrated approach to the natural resources problematic at conceptual, methodological, and operational levels. The Institute is hosted by IXXI, the Complex System Institute of Lyon, the starting point of the expert group for the project.
