Research profile My position of biometrician is at the intersection of three scientific domains: the biology, the statistics and computer science. The biology provides data structures and aims. My role is to search the statistics to find adequate mathematical models, which can be used to develop statistical methods to analyse these data structures, to fulfill the biological aims. Finally, I program the developed methods on computer, so that they can be used to achieve the stated objectives. During my Ph.D. I mainly studied the ways to identify the difference of structures of two clouds of points in a multidimensional space, in the framework of Ecological niche analysis. I pursued some of these research during my Post-doc. Presently, I am also interested in the statistical methods that can be used to analyse GPS data.
