Research

My PhD focuses on investigating the relationship between inflammation, DNA methylation and cognitive decline using computational approaches in large cohorts and analysis of post-mortem brain tissue. Ricardo Marioni (IGMM) is my primary supervisor.

The project has two main objectives:

  • to determine the relationship between blood-based inflammatory biomarkers and inflammation-related genetic and epigenetic signatures, and investigate their associations with cognitive ability and decline in older age;
  • to investigate the DNA methylation profiles in various brain regions to establish the tissue, and region, specificity of age-and inflammation-associated methylation patterns and how these relate to neuro-immune processes within the brain.
