Curriculum vitae

I am an ecologist working on the interactions between soil macrofauna, microorganisms and plants in a multidisciplinary way, mobilizing genetics, physiology, ecology, evolution and soil sciences. Based on this fundamental knowledge, I also develop applied ecological engineering and agroecology projects, such as the establishment of constructed Technosols or the development of alternatives to synthetic inputs in agriculture. My work on species interactions, in particular the emission of signal molecules implicated in the effect of earthworms on plant growth, convinced me that ecological entities like communities and ecosystems could be units of selection. For the past ten years, I have been particularly interested in the natural and artificial selection of microbial communities and ecosystems. My main theoretical influences are Nietzsche, Morin, Latour, Darwin, von Bertalanffy, Odum, Lavelle, Wade, Goodnight and many others.



I am teaching approximately teach about 200 hours/year since 2007, in various disciplines such as ecology, evolution, statistics, plant physiology, soil ecology, ecological engineering. Half of this time is devoted to lectures and the other half to practical work and project-based learning. Two-thirds of this teaching is dedicated to students from four different masters and two final-year agricultural engineering courses. My teaching is organized around three objectives: (i) to provide students with solid basic knowledge in academic scientific disciplines such as ecology and evolutionary biology to design new anthropized ecosystems adapted to global changes; (ii) train students in tools and methods such as documentary research, statistics and modeling of ecological functions, etc.; (iii) to develop their expertise in agronomy and environmental management through ecological engineering courses and debates on current issues of agroecology or evolution.
