Summary

My group investigates why the aged brain is vulnerable to neurodegeneration and asks whether we can alleviate this susceptibility. We focus on the role of key homeostatic neural-circuit plasticity processes thought to be critical for healthy network function.

 After graduating from Oxford University in 2006 I was awarded an MRC Capacity building Ph.D. studentship at King’s College London to investigate synaptic connection loss and neural plasticity in the cortex. I then completed a post-doc investigating how homeostatic plasticity regulates neural activity in the adult visual cortex at University College London. In October 2015, I won the Edmond J Safra Fellowship which supports early career researchers during their transition to independence. In April 2018 I was awarded a UK Dementia Research Institute Fellowship and became a lecturer in the Division of Brain Sciences at Imperial College London. Here, I use a combination of in vivo voltage and calcium imaging, bioelectronics and electrophysiology to investigate the neural-circuit plasticity factors that make the aged brain susceptible to neurodegeneration and ultimately dementia.
