Abstract :
The central question of my research activity concerns the interactions between the living matter and its physical environment, until recently at the single cell scale and now on also at the scale of individuals (schools of fish). A subsidiary question concerns the propagation and processing of information in living organisms. My approach is mostly experimental, combining the development of innovative instrumental methods with the development of new image analysis methods for the quantification of dynamic phenomena. Relying on my training as a physicist to go beyond a simple image analysis, I always try to extract all the information contained in an experimental acquisition.
