Accelerating the development of new treatments
Most dementias are degenerative (wear and tear of brain cells) with a build-up of harmful junk proteins and chronic brain inflammation. Higher brain inflammation is linked to more severe symptoms and faster decline over time. Anti-inflammatory or immunity-based treatments might slow or prevent decline. But better tests to measure inflammation are needed to identify who may benefit most from these treatments, when to treat, and importantly which part of the immune system to target. The Malpetti Lab use specialist brain scans and novel blood tests to measure inflammation in volunteers with different dementia types, to accelerate the development of new treatments.

Research summary
Inflammation in frontotemporal dementia and related disorders: mechanisms, biomarkers and clinical trials
Neuroinflammation is an important pathogenic mechanism in neurodegenerative diseases. However, immunotherapeutic strategies are hampered by lack of knowledge about individual differences in inflammation, their causes and consequences. Dr Malpetti’s studies with PET imaging strongly support the role of central nervous system inflammation in accelerating disease progression in people with Alzheimer’s disease, frontotemporal dementia and primary tauopathies. In people with these conditions, a range of anti-inflammatory treatments could be helpful to slow or prevent decline.
The Malpetti Lab are investigating diverse methods to measure inflammation integrating clinically relevant and mechanistically informative neuroimaging and blood-based markers in people with frontotemporal dementia and primary tauopathies, capturing immune signatures, their interplay with pathology and downstream effects, including synaptic loss and clinical decline. Establishing inflammatory “fingerprints” in people with dementia will facilitate accessible and scalable biomarkers to support personalised medicine, early screening strategies, and target-specific immunomodulatory therapies. To this end, she has established and is leading the 'Open Network for Frontotemporal Dementia Inflammation REsearch' (ON-FIRE). The team applies longitudinal statistical models and multimodal imaging analyses, with an interdisciplinary approach that integrates imaging and clinical data with fluid markers and post-mortem pathology.
Main programme aims:
The Malpetti Lab's overarching aim is to accelerate new treatments for frontotemporal dementia and related disorders. Specifically the team aim to:
- Characterise the predictive value of in vivo PET imaging for inflammation, molecular pathology and synaptic loss in frototemporal dementia, Alzheimer’s disease and related conditions
- Identify novel clinically viable and mechanistically relevant PET and fluid-based biomarkers in dementias to empower target discovery and clinical trials
- Investigate brain and immune changes in pre-symptomatic genetic frontotemporal dementia for early interventions

Dr Maura Malpetti is looking for an enthusiastic Post-Doctoral Research Associate or Research Assistant to join her lab at the Department of Clinical Neurosciences of the University of Cambridge. The post is part of a Cambridge-based program aiming to investigate neuroinflammation in frontotemporal lobar degeneration and accelerate the development of treatments for dementia. To this end, we also recently established a multi-centre study, the UK-wide Open Network for Frontotemporal dementia Inflammation Research (ON-FIRE), which involves data collection from 22 sites across the UK.
The post will focus on the integration of novel PET and blood-based biomarkers of neuroinflammation, neuropathology and neurodegeneration, and clinical outcomes in models of disease progression in genetic and sporadic frontotemporal lobar degeneration. In this role, you will lead (i) PET imaging recruitment and data analysis in patients with frontotemporal dementia and progressive supranuclear palsy, (ii) the coordination of ON-FIRE and related studies on blood-based biomarkers. You will drive the project, develop and deliver the study's research objectives and be well equipped to present developments and key findings to relevant stakeholders.
For this post, you will have an undergraduate and/or a PhD in neurosciences, psychology, physiology or related discipline. You will have knowledge of neuroimaging, related research methods and applications, and project management skills. Experience in patient recruitment in research studies of dementia or mental health disorders would be advantageous. You will collaborate within a balanced team with post-doctoral scientists, clinical fellows, research nurses and students to ensure efficient research activities across the centre.
For informal inquiries regarding the role, contact Dr Maura Malpetti (mm2243@medschl.cam.ac.uk). The role will primarily be based at the Herchel Smith Building for Brain and Mind Sciences, Cambridge Biomedical Campus, CB2 0SZ. The University values diversity and is committed to equality of opportunity. We particularly encourage women and/or candidates from a minority background to apply for this vacancy as they are currently under-represented at this level within our University.
Closing date: 8th December 2024.

To this end, we recently established a multi-centre study, the UK-wide Open Network for Frontotemporal dementia Inflammation Research (ON-FIRE), which involves data collection from 22 sites across the UK.
As a Post-Doctoral Research Associate, you will lead the statistical analysis and data management for multivariate biomarkers identified using novel biochemical assays, including SIMOA, NULISA, Mass Spectrometry, multiomics and other data generating platforms. The role will involve computational analyses of blood-derived data - not wet-lab analyses on the samples - and leading academic and industry partners, including biochemical laboratory facilities such as the Biomarker Factory at the Dementia Research Institute.
The postholder will develop pipelines to (i) centralise adjunct data from all sites to Cambridge; (ii) combine multimodal data, linking blood samples to NHS digital records, genetics and available neuroimages; (iii) format and share data through the Dementias Platform UK data portal. You will lead computational analyses on biomarkers data, polygenic risk score calculations, and immunophenotyping data. You will drive the project, develop and deliver the study's research objectives and be well equipped to present developments and key findings to relevant stakeholders.
For this post, you will have an undergraduate and/or a PhD in Bioinformatics, Statistics or related discipline. You will have in-depth of knowledge of biostatistics, and related research methods and applications. Experience with machine learning algorithms and strong programming skills using platforms such as MATLAB, R, Bash and Python will be essential.
