Professor David Simon Holder is a Professor of Biophysics & Clinical Neurophysiology who has led the Neurophysiology department at UCH since 1997, undertaking EMG, EEG and nerve conduction studies, and a multidisciplinary neurophysiology/bioengineering research group in Medical Physics at UCL, developing new methods to image function in the brain and peripheral nervous system. Currently funded by the Medical Research Council, National Institutes of Health USA, Glaxo Smith Kline and Google Health, his research has pioneered the new method of Electrical Impedance Tomography, a new tool in clinical neuroscience providing 3D images of fast neural activity over milliseconds in the brain and peripheral nerves.

Professor Holder is jointly qualified in Clinical Medicine and Biophysics from Cambridge University and University College Hospital, undertaking a Master's degree in Biophysics at the University of California, Berkeley and a PhD in Physiology at UCL. He held an MRC training fellowship and then Royal Society University Research Fellowship at University College London before taking a position as Consultant in Clinical Neurophysiology at the Middlesex Hospital and UCH.
