Sylvain GIRAUDET

RENNES

En résumé

Since 2009, I'm an associate professor in Rennes, France. Either research and teaching activities are focussing on environmental and chemical engineering. A special expertise was developped for water and air treatments, and especially the processes occuring at the solid-fluid interfaces.
