My scientific interests lie in population ecology, which is a major sub-field of ecology dealing with the dynamics of species populations and how these populations interact with the environment. More precisely, my research focuses on identifying the factors determining the presence, abundance and population dynamics of terrestrial mammals. By doing this, my goal is not only to generate results relevant to the academic world, but also to use the generated knowledge to inform conservation policy and management.
I completed my PhD at the Laboratory of Biometry and Evolutionary Biology in Lyon, France. My Ph.D. project aimed at describing and quantifying the impact of spatial variation in habitat quality on the individual performance and dynamics of a roe deer population monitored for more than 25 years in the south west of France (Chizé). This interdisciplinary Ph.D. (which involved nutritional ecology, botany, population dynamics, management, spatial statistics and multivariate analyses) was the result of the collaboration between the Centre National de la Recherche (CNRS) in Lyon and Chizé (Drs. Gaillard, Duncan, Chessel, and Dray), the Office National de la Chasse et de la Faune Sauvage (ONCFS), and the Office National des Forets (ONF).
My two Postdoctoral positions at the Centre for Ecological and Evolutionary Synthesis, (CEES, University of Oslo, Norway), were successively funded by the French Ministry of Foreign Affairs (Lavoisier fellowship) and a European fellowship (Marie Curie). They focused on the use of satellite-based data (Normalized Difference Vegetation Index, NDVI) in ecology, more particularly in population dynamics of large herbivores (reindeer, roe deer, red deer). More specifically, the aim was to quantify the relationships between vegetation dynamics, seasonal dispersal and individual performance at multiple spatial and temporal scales. This project was among the first ones examining the use of satellite data in vertebrates’ population dynamics, and such work was made possible thanks to collaboration with many universities (i.e. Oslo, Tromsø, Svalbard, Lyon, and Ås).
After spending 8 months at Laval University (Quebec) addressing similar questions to those worked on in France and Norway, I joined the Institute of Zoology in April 2006, and started to work on cheetah demography in the Serengeti National Park, Tanzania. This new project allowed me to apply the key methodologies I have developed as part of my previous work to carnivores, a relatively diverse and culturally and economically important taxonomic group of mammals that has not been studied in as much detail as the large herbivores I worked on previously.
So far I have published more than 60 publications in peer-reviewed journals, and several contributions such as book chapters or reports. My aim is to conduct high quality, innovative and internationally recognized research through a multi-disciplinary approach involving statistics, remote sensing and programming. Over the last years I have been increasingly involved with understanding the impacts of environmental change on biodiversity level and distribution, combining my experience in spatial analysis, remote sensing data and modelling. My extensive experience of NDVI and its usefulness in ecology also drove my recent interest in promoting a better integration of satellite-based data in global monitoring programs, as the information encapsulated in such indices can provide valuable and needed information to wildlife managers and policy makers. I have therefore been increasingly involved in developing projects and producing literature at the interface between science and environmental policy.
I currently supervise 8 PhD students
, and was involved in the supervision of several Bsc and Master students.
I am working on my first book "en solo", entitled "The Normalised Difference Vegetation Index: principles & ecological applications". I hope to get it in press later this year
Have a look at the Virtual Issue I edited for Journal of Applied Ecology here
Our book is nearly there - should be out this year
Our recent article on mangrove degradation was covered by the Guardian
