Dr. Polytimi Frangou

Dr. Polytimi Frangou is a Sir Henry Wellcome Postdoctoral Fellow working in the Stagg group and collaborating with the Tan group. Polytimi’s fellowship looks at the neurochemical origins and oscillatory signatures of abnormal visual processing and visual hallucinations in Parkinson’s disease. She uses magnetic resonance spectroscopy (MRS), pharmacological interventions, non-invasive brain stimulation, magnetoencephalography (MEG) and intracranial recordings.

Polytimi studied Electrical and Computer Engineering at the National Technical University of Athens (2012), before completing her PhD in Cognitive Neuroscience with Zoe Kourtzi at the University of Cambridge (2018). Her doctoral work looked at the role of neurotransmitter GABA in visual plasticity during training, using multi-modal brain imaging (MRS, fMRI) and transcranial direct current stimulation.
