Research Topics
Aspirin and other anti-platelet drugs
We brought together all trials of antiplatelet drugs to show how treatments like aspirin reduce major vascular risks and to provide clinicians with reliable evidence.
Dementia and other neurodegenerative diseases
Our research focuses on the role of vascular risk factors in dementia and on the methodology of assessing cognitive status in very large-scale studies.
Diet, nutrition and obesity
We investigate how obesity, diet, and nutrition affect health and healthcare systems, and have investigated population-level interventions to promote healthier eating.
