Claire Thornton leads the Neurocellular Stress group, focused on deciphering the molecular mechanisms underlying brain injury after metabolic and other stresses. Her research centres on understanding the consequences of pathological alterations in neuronal energy metabolism and mitochondrial function, with the ultimate aim of identifying novel targets for neurotherapeutic intervention.
Following undergraduate Biological Sciences and postgraduate Human Molecular Genetics degrees, Claire Thornton completed her PhD at Imperial College with Prof David Carling (Imperial) and Dr Mike Snowden (GSK) in 1999 on the regulation of the mammalian cellular "fuel gauge", AMPK. Claire then carried out postdoctoral research at University of California, San Francisco, working on neuronal signalling perturbed by drugs of addiction, with Prof Dorit Ron. She returned to the UK, continuing in the field of neuronal cell stress as an Investigator Scientist at the MRC Clinical Sciences Centre and, in 2007, was awarded a Research Into Ageing Fellowship to investigate the role of AMPK-mediated tau phosphorylation as an early event in Alzheimer’s disease. Claire subsequently took up a lectureship at King’s College London where she investigated the molecular basis of Perinatal Brain Injury in response to birth asphyxia, before being appointed as Senior Lecturer in Cell and Molecular Biology at the RVC in October 2018 focussing on neurocellular stress. Claire continues to work on mitochondria and cell signalling mechanisms in neonatal brain injury in response to a variety of stresses such as hypoxia-ischaemia, toxicant and pollution exposure.
Claire is a Fellow of the Higher Education Academy, and a member of the Biochemical Society, the British Neurosicence Association, the British Cell Biology Association and the Society for Neuroscience.
Claire's research interests centre on the molecular basis of neurocellular stress, and the impact of pathologies resulting in neural energy depletion. In particular, her research targets perturbations in mitochondrial dynamics affecting their fission, fusion and mitophagy with the ultimate aim of generating new targets for neuroprotective intervention. Currently, Claire's lab is focussed on understanding cellular energy impairment underlying the development of brain injury in babies following i) asphyxia during birth, ii) exposure to air pollution and iii) exposure to drugs of abuse.
Research in the Neurocellular Stress Group is supported by grants from the Medical Research Council, Action Medical Research and the Royal Society.

Cellular mechanisms of impaired neurodevelopment following early life exposure to air pollution
UNICEF estimates that over 100 million infants worldwide are exposed to toxic air pollution. We are investigating how this alters vulnerable brain cell development during pregnancy and after birth. Air pollution is a serious common public health concern increasingly associated with morbidity and mortality and resulting in an estimated 7 million premature deaths per year. Air pollution is a mixture of several components, including particulate matter (PM) derived from traffic, fuel burning and industry. The World Health Organisation identified that over 90% of the population are exposed to levels of PM2.5 that are significantly higher than recommended levels.
