Objectives

The purpose of our research is to identify groups of individuals who are at high risk of developing three common and tightly linked neurological and vascular conditions, dementia, stroke and venous thrombosis, to discover novel etiological factors and therapeutic targets, and to propose more personalized preventive strategies through improved risk stratification.

Research areas

Our research program relies on major components:

  • Large-scale epidemiological and clinical cohorts coupled with biosamples;
  • The deployment of cutting-edge high-throughput technologies for deep molecular phenotyping;
  • The application of advanced statistical methodologies;
  • A group of experts in molecular-clinical epidemiology;
  • A widespread network of collaborators that enables us to contribute to the functional characterization of the identified biomarkers.

Our project is focusing on three inter-related clinical outcomes, cognitive impairment / dementia, stroke, and thrombosis and is organized around 4 themes:
