Professor David Holder and his interdisciplinary research group at University College London have been working on a new method of imaging fast electrical activity in the brain: Electrical Impedance Tomography (EIT). Professor Holder won a grant from the Epilepsy Research Foundation in 2003 for £146,058 to work on this imaging technique.

Professor Holder is professor of biophysics (which uses the principles of physics to understanding the way the body works) at University College London. He is also professor and honorary consultant in clinical neurophysiology (carrying out EEG reporting, nerve conduction studies and electrical recording of muscle activity) at University College London Hospitals.

At Epilepsy Research UK's evening lecture in Southampton on 10 October 2007, Professor Holder spoke about why he thought a new imaging method was necessary and his nearly 20 years' work to develop it.
