Research in a Nutshell

I am a tenured Chancellor’s Fellow with a background in Epidemiology and Biostatistics. My primary research goal is to use computational models to understand the molecular mechanisms that underlie Alzheimer’s disease and to enhance prediction of the disease.

I have a passion for research into ageing and, in particular, examining the genetic and environmental contributions to health, cognitive ageing, and dementia. My group’s work is at the intersection of the biomedical and social sciences.

In recent years, much of my research has focused on DNA methylation – chemical changes to DNA that turn genes on and off and that can be added and removed over the lifespan. These methylation marks can be influenced by genes, lifestyle, and the environment, making them ideal candidates to help us understand the interaction between nature and nurture.

Much of my group’s work is carried out using data from population-based cohorts, such as Generation Scotland, the Lothian Birth Cohorts of 1921 and 1936, and UK Biobank.
