Neurogenomics
All major neurodegenerative diseases are characterised by substantial heritability and large-scale genetic efforts have identified variants associated with disease. These often lie in non-coding, regulatory regions and cannot be linked to any functional outcomes.
At the Centre, we have four groups exploring distinct but complementary areas within this scope of research. Read more about each of them below.

Dr Raffaella Nativio
Epigenetic pathways in healthy ageing and neurodegeneration
Research in my laboratory is directed towards studying epigenetic regulation in healthy ageing and age-related neurodegeneration. I will perform a series of multi-omics and functional genomics studies in post mortem brain tissue in combination with in vitro experiments to identify epigenetic pathways that modulate (either promote or protect from) Alzheimer’s progression. In vitro experiments will also be performed to identify specific stress response pathways in different brain cell types.

Dr Alexi Nott
The role of genetic variation in brain ageing and disease
My group have established a protocol for isolating nuclei of specific cell types from human brain tissue to generate promoter-enhancer interactome maps which have given exciting insight into genes influenced by AD-risk variants and revealed probable cell types in which they function. My overarching vision is that human cell type-specific enhancer atlases will reveal the function of disease-risk variants and identify signalling pathways and transcription factors associated with disease.

Dr Nathan Skene
Seeking drug targets for neurodegenerative disease with genome-wide directional evidence
The overall aim of my programme is to identify regulatory mechanisms which cause neurodegenerative disorders, along with the cell types in which they act, and determine whether inhibition or activation of the pathway is associated with increased disease risk. The first step will be to define the cell types responsible for initiating or sustaining the disease, the second step will be to identify transcription Factors acting within the disease-associated cells.

Dr Sarah Marzi
Epigenetic regulation of environmental and genetic risk in neurodegenerative disease
While environmental factors are recognised to be important for neurodegenerative disease outcomes and are known to influence epigenetic regulation, specific epigenetic mechanisms through which environmental factors may promote neurodegeneration have not been defined well. My research will address this knowledge gap directly for the first time by characterizing the epigenetic mechanisms by which environmental risk factors confer disease risk and interact with the underlying genetic risk profile.
