Name: Professor Pat Kehoe

Role: Joint Head of Group/Elizabeth Blackwell Institute Director

Biography: Pat was one of the first graduates at University College Dublin, Ireland, to complete a new Joint Honours Degree programme in Genetics and Pharmacology before completing his PhD from the Department of Psychological Medicine in the former University of Wales College of Medicine (now part of Cardiff University) in 1998. After his PhD on the molecular genetics of Alzheimer’s disease and a period as an MRC-funded post-doctoral researcher working on some of the first sibling pair linkage studies of Alzheimer’s disease he took a career break to work as an NHS Research & Development Manager for the Avon and Wiltshire NHS Partnership Trust. In 2003 he returned to academia as the Gestetner Research Fellow to lead what was a much earlier incarnation of the current group where his research has focused the role of the Renin Angiotensin System in Alzheimer’s disease following his PhD studies based-seminal paper of genetic association between variation in the ACE-1 gene and Alzheimer’s disease risk. This included work spanning genetics, neuropathology, biochemistry and pharmacoepidemiology and culminated in an NIHR EME-funded Phase II randomized controlled trial on which he was Chief Investigator.  He has jointly led the group since 2006 whilst serving in the last decade as Head of Section and Research Director for the Bristol Medical School, and more recently Faculty Research Director for the Faculty of Health & Life Sciences, playing a key role in the development of the new research strategy for the faculty formed in 2023.

Name: Dr Scott Miners

Role: Joint Head of Group/ARUK Senior Fellow

Biography: Scott joined the Dementia Research Group in 2005 after completeing his PhD in Medical Biochemistry at the University of Cardiff. During his first post-doctoral position, Scott developed assays to measure the enzyme activities of Aβ-degrading enzymes in the brain in Alzheimer’s disease (AD). This research led to him being awarded a Alzheimer’s Research UK (ARUK)  junior fellowship in 2013. During this time he was also heavily involved in work mapping changes in the classical renin-angiotensin system (RAS) within the brain in AD. In more recent years, his attention has turned to characterising changes in the protective regulatory arm of RAS and is now focussed on mapping cell-specific changes in RAS receptors within the brain in AD.  In 2015 his research focus changed direction as he became interested in the role of cerebrovascular dysfunction in AD. Scott was instrumental in helping develop a novel panel of biochemical markers to assess cerebrovascular function in dementia. His work has led to numerous publications revealing novel insights into the pathophysiology of cerebrovascular changes in AD. In 2019 he was awarded an ARUK senior fellowship to study the timing and cause of pericyte degeneration and blood-brain barrier leakiness in AD. His fellowship has fostered collaborations with clinical colleagues and he has a growing interest in developing CSF and blood-based markers of cerebrovascular injury for early detection of AD. Scott has recently been funded to undertake a major study using sn-RNA Seq to map changes in gene expression within the cerebral vasculature in relation to disease pathology across brain regions affected at different stages of disease.

Role: PhD Student

Biography: Peter graduated from the University of Exeter in 2022 with a BSc in Medical Sciences with a professional training year.

During his professional training year, he investigated gene expression changes in motor neurons from patients with Amyotrophic Lateral Sclerosis, as well as the crossover between these perturbed gene expression programs and expression changes as neurons age. For his final year project, Peter reviewed the use of electrical stimulation to treat pain in fibromyalgia, which also led to a spin off project highlighting the under representation of ethnic minorities in clinical trials for this condition.

Peter joined the ‘Dementia Research Group’ in 2023 as a PhD student investigating the genetics of non-cognitive symptoms in Alzheimer’s Disease. Specifically, his project first aims to identify subgroups of Alzheimer’s Disease patients based on non-cognitive symptom profiles using principal component analysis, clustering methods, and confirmatory factor analysis. Next, he will investigate the underlying genetic associations with these identified subgroups.

Peter’s PhD project is a collaboration with the ‘Dementia Research Institute’ and the ‘Division of Psychological Medicine and Clinical Neurosciences’ departments at Cardiff University.
