Xavier Noblin, CNRS researcher at the Laboratoire de Physique de la Matière Condensée, has been awarded the 2009 prize of the Journal of Experimental Biology for the best published paper ("Outstanding Paper Prize").
This prize, aimed at supporting young researchers, highlights an outstanding work carried out on the role of water drop dynamics in one of the ejection mechanisms of fungi spores. This work permitted to clearly show, thanks to movies involving more than 200000 images/s, how capillarity phenomena are utilized at 10 micron scales by fungi spores. Measurements of their speeds, rotations, as well as of the position of the drop, allowed understanding the complete scenario of this process thanks to the identification of the involved forces. This analysis has been completed by a measurement of a the disruptive force which confirmed the interpretation. Finally, the described model has been confronted to experiments carried out with an artificial, simplified, system.
After his studies at the Ecole Normale Supérieure de Lyon, followed by a Master’s degree in liquid physics at the University Paris 6, Xavier Noblin prepared his PhD thesis work at the Laboratoire Physico-Chimie Curie of the Institut Curie in Paris on anchoring physics under the supervision of Françoise Brochard-Wyart. Before reaching the Laboratoire de Physique de la Matière Condensée in Nice in 2006, he was a post-doctoral fellow in Harvard (Jacques Dumais’ laboratory) during which he made a big part of the experimental work that has been awarded.
