Pebble shapes

Expertise in dealing with the characterization of shapes by means of curvature, as required for the thermal analysis of membrane shape fluctuation, has lead us to collaborate with Philippe Duringer from the Geology Department of Strasbourg and with Douglas Durian from U-Penn in Philadelphia on the explanation and characterization of erosion shapes. Our work [1], [2] was met with a strong interest from the scientific and non-scientific press around the world, from the Daily Telegraph to the Toronto Star, or from Nature News to Le Figaro. Our curvature distribution method has since been studied and used by scientists in Archeology or Geology, and models for the different erosion processes that we addressed have been taken on by theoretical physicists and mathematicians.
