PhD Student at University of Oxford. Ajantha is interested in the cellular mechanisms of Alzheimer's, Parkinson's, and other diseases of the ageing brain. Previously, he looked at neuropathology in dogs with dementia and potential stem cell replacement therapies. He is now using induced pluripotent stem cell derived neurons to try and model selective neuronal vulnerability: the phenomenon where some cells die but others remain resilient to neurodegenerative diseases.
