Geertjan Huiskamp obtained his PhD degree at the University of Nijmegen in 1989 on work on the inverse problem of electrocardiography. After having spent post-doc research at the University of California at Irvine on inverse methods and again at the University of Nijmegen on propagation models for ventricular activation, in 1996 he moved to the department of Clinical Neurophysiology of the University Medical Center Utrecht, the Netherlands, where he got involved in source localization for pre-surgical evaluation of epilepsy patients. Since 2000 he is staff physicist at the department of Neurology and Neurosurgery, University Medical Center Utrecht, where his main tasks are research and technology assessment centered around the invasive epilepsy monitoring unit.
