Research summary
My research combines multimodal imaging techniques (e.g. MEG, EEG, MRI, MRS) with computational modelling (e.g. DCM) and machine learning methods to better characterise healthy and diseased brain function on a multi-scale level. I am particularly interested in understanding the link between synaptic physiology and neural oscillations.
My experimental imaging studies to date have included the study of psychiatric (MDD, SABP, Schizophrenia) and neurological (frontal-temporal dementia, progressive supra-nuclear palsy) disorders, as well as placebo-controlled pharmacological imaging studies (ketamine, tiagabine, propofol).
