Dr. Ashwini Oswal

Academic Clinical Lecturer in Neurology

Ash studied Neurophysiology at the University of Cambridge, before completing his medical studies at University College London. He undertook his early clinical training in Cambridge and Oxford, prior to studying for a D.Phil. in Clinical Neurosciences at the University of Oxford (advised by Professor Peter Brown at Oxford and Professor Vladimir Litvak at UCL). During Ash’s D.Phil., he used a combination of magnetoencephalography (MEG), electroencephalography (EEG) and deep brain recordings in people with Parkinson’s to investigate the brain network effects of Deep Brain Stimulation (DBS) used to treat the disease.

Following on from Ash’s D.Phil. studies, he started specialist training in Neurology and was subsequently awarded an Academic Clinical Lectureship allowing him to continue with research alongside clinical practice. He also plays an active role in teaching undergraduate medical students at the University of Oxford.

Key Research Areas

Ash’s research aims to use imaging, computational and electrophysiological approaches to discover how neurological disease phenotypes relate to specific brain network abnormalities. This is likely to be important for both improved diagnoses and the discovery of novel treatments.

Ash is currently interested in answering the following research questions: (1) How do bursts of abnormally synchronized activity that are likely to be detrimental to movement arise within the basal ganglia in Parkinson’s disease? (2) Can prediction of the timing of bursts be used to improve the effectiveness of treatments such as Deep Brain Simulation? (3) How does dopamine impact memory formation and replay within the brain? (4) What neuronal processes lead to abnormalities of memory formation in neurological diseases such as Parkinson’s?
