Sarah Marzi is an Edmond and Lily Safra Research Fellow and UK DRI Emerging Leader at Imperial College's Dementia Research Institute. She is interested in epigenetic regulation in neurodegenerative disease, focussing specifically on the molecular drivers of Alzheimer's and Parkinson's disease. The Marzi lab uses a combination of wet lab and computational genomics approaches to understand the regulatory consequences of environmental and genetic risk factors of neurodegenerative disease. Dr Marzi leads the Experimental Models Working Group of the DEMON network.
Dr Marzi graduated in mathematics and psychology from the University of Freiburg, Germany, before undertaking a PhD at King's College London with Jonathan Mill. Her work looked at epigenetic signatures in human brain associated with ageing and neurodegeneration, as well as DNA modifications associated with early-life stress and victimisation. She identified widespread differences in histone acetylation in Alzheimer's disease compared to neuropathology-free brain, linking these epigenetic marks with genetic risk burden and gene expression signatures.
Her postdoctoral work with Vardhman Rakyan at Queen Mary University of London focussed on gene-environment interactions following developmental nutritional stress. Specifically, she worked on the assembly, genetic and epigenetic characterisation of ribosomal DNA in human and mouse, and investigated the role of methylomic correlates of paternal obesity in influencing offspring health.
