About
As a neuroscientist and stem cell biologist, I am a Associate Professor in Stem Cells and Neurobiology, Principal Investigator, linking my basic research to industry and clinical needs, as well as integrated PhD programme lead, MRC DTP deputy lead and Doctoral Programme Lead.
Having graduated in Biology from the Ecole Normale Supérieure de Lyon, France, I completed my PhD in Neurosciences at the University of Paris VI, France, working on intracellular signalling pathways during neuronal apoptosis I then moved on as postdoctoral fellow in Professor Derek van der Kooy’s team in Toronto, Canada, working on neural stem cells during development, in the adult brain and in different pathological conditions, before joining Southampton.

Research groups
Current research
I lead a research group that investigates the role of the microenvironment on the activity of stem cells in the developing, adult or pathological brain. I am part of the Centre for Human Development, Stem Cells & Regeneration and the Southampton Neuroscience Group. My research group is based within the Southampton General Hospital and comprises clinical, non-clinical and industry scientists.
Role of maternal diet on regulation of offspring foetal neural stem cells and brain development
Early studies suggest an effect of maternal low protein diet on the overall brain growth and cell cycle. Generation of astrocytes and mature neurons is also affected by protein restriction during gestation. These and our data suggest that neural stem cells activity is affected by a maternal low protein diet. Our hypothesis is that a maternal low protein or high fat diet during gestation, and possibly just during the periconceptional period, affects the development of the brain and the regulation of neural stem cells across life. In particular, the project examines whether the maternal diet regulates in vitro and in vivo proliferation, self-renewal, differentiation and migration of the offspring neural stem cells at different ages, using techniques such as sphere assay, immunocyto/histochemistry, FACS, videomicroscopy, migration assays, in vivo labelling and imaging.
A human iPSC derived-3D neural model to study cellular and biochemical aspects of the pathology of Alzheimer's Disease's pathology
Treatments developed in animal models of Alzheimer’s disease fail to translate to patient therapies, possibly because there are significant differences between animal and human brains and proteins. To counteract this, patient-derived induced pluripotent stem cell (iPSC) can be used to generate human neuronal models. We compare and contrast aspects of the structure and function of iPSC-derived neurons grown in 2D and 3D culture, with those of human resected tissue. We focus on aspects of tau biology and synaptic function to generate a gold standard for these disease-related parameters in living adult human neurons. We generate a 3D iPSC-derived neural model to study some cellular and biochemical aspects of the pathology of Alzheimer's disease.
