Mobility project

Unravelling the role of epithelial and microbial proteases on microbiota biofilm dysbiosis associated with alimentary infection caused by pathogenic Escherichia coli

The relocation to France is the second major move on my ‘personal path’ to building a career in biomedical science. I am confident that my drive and ambition to achieve the intellectual and practical goals set out in this project will ensure that this AgreenSkills+ Fellowship will be a crucial period in my progress to professional maturity. I am truly confident that chosen host organisation (IRSD, Toulouse) will provide me all the support and aid I could wish for the satisfactory completion of this project. At the completion of this AgreenSkills+ fellowship, I am confident that I will have reached sufficient professional maturity to be able to apply my skills to important research goals in having scientific and social impact. In doing so, I believe I will have truly matured as a European Scientist, able to address through my research some major health issues of the European Community.

Biography & research interests

I always aspire to become an independent researcher in a national research institutes in France. I am keen to train the future generation of thinkers and to instill in them, a sense of passion for fundamental research in biomedical field. My education and research training to date, has chalked out this clear trajectory for me. This AgreenSkills+ fellowship will help me to achieve this professional goal, by financing my return in France at the Research Institute on Digestive Health (IRSD, Toulouse, INSERM U1220) after 31/2 years of postdoctoral training at the University of Calgary (Alberta, Canada). This support will help me to continue to build on my previous professional experiences and to expand my personal circle of partnerships and collaborations. My research has always been motivated by its potential translational impact, and thus my current project is designed to lead to the discovery of mechanisms and mediators for the treatment of intestinal infection and chronic inflammation. My decision to complete my postdoctoral training at the IRSD – coupled with an AgreenSkills+ fellowship – is thus both strategic and beneficial, as it will help me to achieve my career goals while creating and disseminating new knowledge which will have bench to market to bed expectations.
