PhD : « Statistical methods for measuring biodiversity » University Claude Bernard Lyon I, France, December 2005
I studied mathematics, population and community ecology at the University of Lyon I, France, and obtained my PhD in statistical ecology at the University of Lyon I in December 2005. I moved to the Museum of Natural History as a researcher and lecturer in Paris, France, in October 2005 and obtained a permanent position in June 2006. I spent one year as a Marie Curie fellow at the University of Oxford, UK, (from January 2008 to February 2009) and became research associate in January 2011.

I am particularly interested in developing and studying new mathematical approaches to analyse biodiversity, population and community assembly.
Measurement and analysis of biodiversity : patterns and processes
A myriad of indices (mathematical functions) of biodiversity have been developed. Even the definition of biodiversity is so general that each discipline develops its own rules, definitions and indices. Working on the measure of biodiversity requires thus efficient communications and exchanges among disciplines, including mathematics and biology. In my research, I try to merge disciplines to analyse and measure biodiversity consistently, taking account of temporal, evolutionary or spatial scales. In this framework, I am particularly interested in indices that include measures of abundances and differences among organisms (based on genetics, phylogeny, life history, behaviour, physiology, etc). These researches are made in the contexts of Conservation Biology and Ecology. They also have consequences for any disciplines interested in measuring an aspect of diversity, and they are cited for instance in Genetics, Medicine, Microbiology and also Computer science, Physics, Economics.
Among all aspects of biodiversity, acoustic diversity is particularly under-explored. A classical approach to assess biodiversity richness is to determine the number of species present. However, inventorying all species in a place might be invasive and costly. In contrast, acoustic approaches might be non-invasive, while producing lots of data. Part of the animal biodiversity produces sounds. These sounds can be recorded by field-based sensors. The recorded acoustic data can be used to estimate a level of local acoustic richness. Multiplying the recordings in many places at many times would enable the comparison of levels of biodiversity in space and time. We are particularly interested in developing measures of the complexity and diversity of the sounds recorded (bio-sounds) without species identifications.
Ecology and Community dynamics
The process of community assembly involves ecological, evolutionary and stochastic processes. They structure the functional (trait) and phylogenetic diversities of communities in space and time. Biodiversity partitioning based on explanatory factors and factorial analyses are two key approaches to analyse how communities assemble. Partitioning biodiversity is for instance finding the contribution of a factor to the diversity of a community or to the differences among communities. Factorial analyses are in essence mathematical, geometric, multivariate methods. Under certain conditions, they enable a description of biodiversity at different scales, for instance of the differences among species and communities in terms of genes, traits or phylogenies. My research interest in this field concerns the developments of partitioning and factorial methods to identify traits and clades involved in ecological mechanisms including environmental filtering and limiting similarity.
One aspect of diversity which is increasingly used in conservation biology is phylogenetic diversity. It is expected that phylogenetic diversity reflects diversity of characters, even characters still unidentified. Measures have been developed to provide an overall assessment of the phylogenetic diversity of a set of species and its future. Another point of view focuses on the contribution of each species to the phylogenetic diversity, leading to the notion of originality of a species. A species is original, from a phylogenetic point of view, if it belongs to a lineage with little or no sibling species. A typical example of such species is the platypus Ornithorhynchus anatinus in mammals. I am particularly interested in analyzing the human-driven threats that may impact the future of phylogenetic diversity and originality of different taxa including mammals.
