I am an experienced researcher with strong interests in conservation biogeography, spatial and landscape ecology, and biodiversity monitoring.

Professional pathway

titeux_rI successfully defended my PhD thesis in science in June 2006 at the Université catholique de Louvain (Belgium). Next, I was awarded a highly competitive fellowship obtained from the Belgian Fund for Scientific Research to conduct post-doctoral research in collaboration with scientific institutions in Finland and Switzerland.

In 2008, I was hired for a permanent position as a project leader at the Centre de Recherche Public – Gabriel Lippmann to establish and coordinate the national biodiversity-monitoring programme in Luxembourg.

In 2014, I moved to the Biodiversity and Landscape Ecology lab of the Forest Sciences Centre of Catalonia (Spain). As a representative of the European Bird Census Council (EBCC), I coordinated a LIFE project funded by the European Commission to develop the EuroBirdPortal and I participated in several international projects and initiatives.

Since 2017, I am working at the German Centre for Integrative Biodiversity Research (iDiv) to provide scientific support to one of the co-chairs of the Global Assessment report produced by the Intergovernmental Platform on Biodiversity and Ecosystem Services (IPBES).

Main research lines

  • Understanding and predicting the impacts of global environmental change on ecosystems and biodiversity across a range of spatial and temporal scales
  • Combining and analysing structured and unstructured biodiversity observation data to improve our understanding of biodiversity dynamics in space and time
  • Evaluating the roles played by different factors in driving changes in the state of biodiversity across spatial scales
  • Comparing the pros and cons of local and global approaches to understand and predict the impacts of environmental change on ecosystems and biodiversity
  • Understanding habitat selection patterns and processes in human-modified environments
