The primary aim of my research is to understand the genetic basis of complex neurological disorders, with a special emphasis on stroke, dementia and cerebral small vessel disease. I am a statistical geneticist and use approaches starting from candidate genes, genome wide association studies to whole exome sequencing to identify rare and common genetic variants in genes responsible for complex genetic disorders. I have been performing large scale genome wide association studies and trans-ethnic meta-analysis of genome wide association studies as part of collaboration with CHARGE consortium and other large consortia in Prof. Debette’s lab since 2012. I have performed whole genome imputation using the 1000G reference panel and I am currently analyzing whole exome sequencing data for the French population based cohort of 3C-Dijon.
