The dynamics of life is a fascinating puzzle unfolding at multiple scales. Biological systems involved in perception and behavior also underlies our ability to grasp meaning from the world. They amaze me by their robustness in sensing their environment, for example, for photosynthesis or vision, and they inspire me to develop new technologies and discover new scientific perspectives on animals, plants and microbes in their respective ecosystems.
I currently develop artificial intelligence and robotic systems to help people managing micro-farms. Farmers and plant biologists are both experts at growing plants although they rarely exchange their knowledge. I aim at bringing them together around new technologies so that their knowledge can be transferred. I design new hardware to intervene on crops and acquire in-field data. These data are then integrated through mathematical modeling to get a useful description of the field and to point the farmer to the possible actions he can take. I also hope to surprise biologists and farmers about how machines might teach them about the biology of wild plants.

Profile

David Colliaux studied mathematics and physics at Ecole Polytechnique and cognitive sciences at the Ecole Normale Supérieure Paris. As a Ph.D. student, he studied mathematical models in cognitive neuroscience and he wrote his dissertation on the impact of visual experience on on-going dynamics of the primary visual cortex. He worked further on learning and evolutionary dynamics as a fellow of the Japan Society for the Promotion of Science (JSPS) at the University of Tokyo and then joined Collège de France and the Institute for Intelligent Systems and Robotics (ISIR) in Paris to study biological computations in micro-organisms as a model for micro-robots. At Sony CSL, he is working in the sustainibility group to create tools for an adaptive management of agro-ecosystems.
