RESEARCH INTERESTS
I have started my research in the human movement sciences, with a particular interest in motor control and timing, motor coordination, learning, but also (perceptually-based) anticipation. I approached these topics from the perspective that motor behavior, which is by definition constituted by patterns that can be viewed as macroscopic relative to the scale of the ‘wetware’ within which it arises (i.e., the ‘stuff our bodies are made of, including muscle and neural tissue [at various levels of description]), and emerges due to the multitude of interactions on far smaller scales (i.e., those making up the ‘wetware’). In other words, I conceptualize motor behavior as a manifestation of self-organized pattern formation in open systems. Or, in James Gibson’s terms, “control without a controller”.
I formally switched from human movement science to ecology in 2021. (I am grateful to both my employer, the Centre National de la Recherche Scientifique [French National Research Center] as well as the SETE, for having allowed, supported, and welcomed me.) My current research focuses first and foremost on the fate of organic matter, in particular carbon, as it decomposes, is respired to fuel photosynthesis, or interacts with the soil matrix by forming organo-mineral complexes through interactions with soil metals and minerals or find shelter from decomposer organisms in soil aggregates. In continuation herewith, I have started studying how plants, and more particularly, plant communities of varying specific as well as functional diversity interact with soils and co-determine their functioning.
