DESCRIPTION:Prof. José Bico\, PMMH-ESPCI\nAbstract:\nCartographers have e
 arly realized that it is impossible to draw a flat map of the Earth withou
 t deforming continents. Gauss later generalized this geometrical constrain
  in his Theorema Egregium. Can we invert the problem and obtain a 3D shape
  by changing the local distances in an initially flat plate? This strategy
  in widely used in Nature: leaves or petals may develop into very complex 
 shapes by differential growth. From an engineering point of view\, can we 
 induce similar shape changes by inflating a network of channels imbedded i
 n a deformable flat patch? Can we program the final inflated shape?\n\nBio
 :\nJosé Bico\n- 1997-2000 PhD at the Collège de France (supervision Davi
 d Quéré)\n- 2001-2003 Postdoc in the Department of Mechanical Engineerin
 g\, MIT\, USA (supervision Gareth McKinley)\n- since 2003 associate profes
 sor à ESPCI-PSL (École Supérieure de Physique et de Chimie Industrielle
 s de Paris\, Paris Science et Lettres)\n\nDeveloped "MecaWet" research gro
 up in the PMMH laboratory (Physique et Mécanique des Milieux Hétérogèn
 es) with Benoît Roman and Étienne Reyssat\, where we work on the mechani
 cs of slender structures (“Meca”)\, interfacial flows (“Wet”) and 
 the coupling of mechanics and surface forces.\nCo-author with Étienne Guy
