Bastien TRAN is an ecological engineer. After achieving his master’s degree in Ecology, Biodiversity & Evolution (Conservation Biology, Paris VI) he enrolled for the masters degree “Space and Environment” (Paris VII) in order to clarify the relationships between human societies and biological diversity. Employed at the National Museum of Natural History (Paris) he worked on different stages of the biological data path; from it’s sampling to its synthisis but especially its diffusion. Aware that the appropriation of environmental stakes must go through the sharing of frequently complex information thus requiring information and knowledge mediation, Bastien joined REEDS in late 2011 as a PhD student in order to commence a doctoral thesis within the DIGISCOPE project framework under the supervision of Martin O’Connor.
