The position is open within the frame of one research program: HEROIC dealing with Crohn’s Disease.
Crohn’s Disease (CD) is a chronic inflammatory bowel disease with unknown cause which concern 3 billion persons in the world. Although more than 160 genes have been associated, they only explain a part of the incidence. Significant variations of CD’s frequency are observed, suggesting the role of environmental risk factors. Literature points limited epidemiological data that requires further studies. Using the world’s largest population-based study on CD incidence (EPIMAD Registry ≈ 15000 records since 1990), we highlighted a spatial heterogeneity with epidemic areas and low incidence areas.

The HEROIC Project

The main objective of the HEROIC project is the identification of environmental risk factors using geospatial analyzes carried out from the EPIMAD Registry data. This identification will involve a transversal and multidisciplinary approach, including a geographical ecological study.
The candidate will focus on the geographical ecological study and will aim to identify environmental risk factors related to the quality of the environmental compartments involved in the development of CD.  
More precisely, this general objective is divided into two ambitions which are: - to clarify the role of environmental quality in the occurrence of the first outbreak of Crohn's disease; - to evaluate the role of environmental quality in the natural history of the disease, that is to say, to diagnose the evolution of the patients and the disease according to the quality of the environment.
To do so, a unique database will be created to characterize the living environment of the population on a cantonal scale throughout the territory of the registry, including a focus on detected clusters of
over-incidence and under-incidence. This database will include spatialized indicators of exposure of the population to long-term air, water and soil pollution, as well as indicators of proximity to sources of pollution. The creation of composite indexes will make it possible to approach the integrated dimension of pollution (cocktail of pollutants).
Multivariate ecological regressions will finally be performed to identify the ecological factors correlated with the incidence of CD.
