INSERM Research Associate, obtained his PhD from the University of Paris VI in 2007, under the supervision of Dr. Bertolotti, in the context of Huntington’s disease. He was then trained as a postdoctoral researcher at the laboratory of Dr. Vila in Barcelona, where his work mainly focused on the molecular mechanisms of neuronal cell death and the mechanism and significance of Lewy body formation in Parkinson’s disease. Since 2010, he has been working in the Institute of Neurodegenerative Diseases Research Group of Dr. Bezard, first as a senior postdoctoral fellow, where he subsequently obtained an Independent Investigator position as an INSERM Research Associate in 2013. Dr. Dehay’s scientific career has been focused to understand how the disease proteins cause alterations of the autophagy-lysosomal pathway, contributing to the pathogenesis for then proposing adapted therapeutic approaches to clear the toxic proteins and halt the disease process. He has a broad expertise in the field and in molecular and cell biology approaches and pathophysiological investigations in animal models including non-human primates, rodent models and on human tissues. Finally, some of the scientific highlights include the study of the progressive spreading of synucleinopathy through disease modeling across species.
