Dr. Joseph Valentino Raimondo MBChB (Cape Town) MSc (Oxford) DPhil Neuroscience (Oxford)

Neurophysiology Research Group

Joseph Raimondo

Research Fellow, Division of Physiology, Department of Human Biology, Faculty of Health Sciences, UCT
& Associate Member of the Institute of Infectious Disease and Molecular Medicine (IDM)

Key areas of expertise:
Neurophysiology, epilepsy, synaptic transmission, plasticity, neurocysticercosis, patch-clamp electrophysiology, optical imaging, neuronal biophysics

Joseph Raimondo is a neuroscientist who investigates brain function and dysfunction using electrophysiological, optical imaging and computational approaches. His career ambition is to produce outstanding research of both local and global relevance, whilst developing African capacity in cellular neurophysiology and computational neuroscience. The primary aim of his research group is to answer the question: ‘Why do brains seize?’ To do so they examine the cellular and circuit level interactions between brain cells, which result in the development of epileptic seizures. They attempt to utilise a ‘first principles approach’ to make predictions that can be tested experimentally. They have a strong focus on causes of epilepsy relevant to the African context, such as epilepsy secondary to cerebral tape worm infection (neurocysticercosis).
